Follow the 60-day CAT exam preparation schedule we prepared for you to get a flow, plan, and schedule for your preparation.

Quantitative Aptitude For CAT 2024

Simple interest(SI) Instalments

Loans and instalments are key topics in financial mathematics and an essential tool to borrow money for various purposes, such as purchasing a home, financing education, or expanding a business.

When you take a loan from an agency and return it in parts after regular intervals. The amount returned at regular intervals is an instalment.

CAT Questions on Instalments and CAT Questions on Loans are categorised based on whether the interest rate is Simple Interest or Compound Interest .

We need to have a clear idea about how to calculate the Simple Interest or Compound Interest of a sum of money.

Simple interest = (Principal × Rate × Time) / 100

Compound interest = Principal × [1 + (Rate / 100)]Time – Principal

Suppose Anil purchased a television worth Rs. 18000 paying Rs. 10000 cash down payment and every month a fixed instalment has to be paid for the next 6 months where interest is charged at 10% per month on simple interest.

You need to calculate the value of EMI.

First, you need to calculate debt (Amount due after 6 months if paid in a single time)

Principal = 18000 – 10000 = Rs. 8000

Debt = 8000 + (8000 × 10 × 6)/100 = Rs. 12800

First instalment after 1st month = Rs. 100x (Let)

Amount due after 1 month = Rs. 12800 – 100x – 100x × 5 × 10/100 = Rs. 12800 – 150x

(Instalment amount and Interest for 5 months have to be subtracted from the amount due since 100x is returned after one month and interest is added for 6 months in the original amount due)

Amount due after 2 months = Rs. 12800 – 150x – 100x – 100x × 4 × 10/100

= Rs. 12800 – 290x

(Instalment amount and Interest for 4 months have to be subtracted from the amount due since 100x is returned after two months and interest is added for 6 months in the original amount due)

Amount due after 3 months = Rs. 12800 – 290x – 100x – 100x × 3 × 10/100

= Rs. 12800 – 420x

(Instalment amount and Interest for 3 months have to be subtracted from the amount due since 100x is returned after three months and interest is added for 6 months in the original amount due)

Amount due after 4 months = Rs. 12800 – 420x – 100x – 100x × 2 × 10/100

= Rs. 12800 – 540x

(Instalment amount and Interest for 2 months have to be subtracted from the amount due since 100x is returned after four months and interest is added for 6 months in the original amount due)

Amount due after 5 months = Rs. 12800 – 540x – 100x – 100x × 1 × 10/100

= Rs. 12800 – 650x

(Instalment amount and Interest for 1 month have to be subtracted from the amount due since 100x is returned after five months and interest is added for 6 months in the original amount due)

Amount due after 6 months = Rs. 12800 – 650x – 100x

(The instalment amount has to be subtracted from the amount but interest is not subtracted since 100x is returned after six months and interest is added for 6 months in the original amount due)

After payment of all instalments, the amount due = 0

So, Rs. 12800 – 650x – 100x = 0

⇒ x = 17.067

⇒ 100x = Rs. 1706.7

Instalments At Simple Interest

To find the value of the annual instalment with Simple Interest , we use the following formula:

Annual instalment = 100A / 100T + [RT(T – 1)/2]

Where A is the total amount to be paid in T years with R% annual interest.

Instalments At Compound Interest

Let a person take a loan from an agency at r% per annum compounded annually and pay the loan in equal instalments for n years.

Then, the value of each instalment can be calculated by the given formula:

Amount due after n years = P (1 + r/100)n

If paid in instalments, the amount due must be equal to

P (1 + r/100)n = X (1 + r/100)n-1 + X (1 + r/100)n – 2 + X (1 + r/100)n – 3 +…. + X (1 + r/100)

Where, X = Instalment value

Questions and MCQs on Loans and advances and CAT questions on Installments (SI and CI) can be divided into sub-categories during CAT preparation:

  • Questions that involve calculations of instalment value.

  • Questions that involve calculations of the rate of interest charged.

  • Questions that involve calculations of debt.

We have to further study topics like “instalment loans for bad credit”, “instalment loan calculator”, and “loan instalment payment” to delve deeper into this chapter. Now we will practice some instalment loan example questions to understand the topic better.

CAT Model Questions And Answers From CAT Previous Year Papers

Question 1. John borrowed Rs. 2,10,000 from a bank at an interest rate of 10% per annum, compounded annually. The loan was repaid in two equal instalments, the first after one year and the second after another year. The first instalment was the interest of one year plus part of the principal amount, while the second was the rest of the principal amount plus due interest thereon. Then each instalment, in Rs., is:

[CAT Question Paper 2018, TITA]

  1. Rs. 121000 (Correct answer)

  2. Rs. 100000

  3. Rs. 120000

  4. Rs. 125000

Great Lakes - PGPM & PGDM 2025

ISBR Business School PGDM Admissions 2025

180+ Companies | Highest CTC 15 LPA | Average CTC 8 LPA | Ranked as Platinum Institute by AICTE for 6 years in a row | Awarded Best Business School of the Year

Solution:

P = 210000, n = 2, r = 10

Let X be the value of the instalment each year.

Using,

P (1 + r/100)n = X (1 + r/100)n-1 + X (1 + r/100)n-2 + X (1 + r/100)n-3 +….+ X (1 + r/100)

⇒ 210000(1 + 10/100)2 = X (1 + 10/100)2-1 + X (1 + 10/100)2-2

⇒ 210000(121/100) = X (11/10) + X

⇒ 2100 × 121 = X (21/10)

∴ X = 121000

Hence, the correct answer is Rs. 121000.

Question 2. Rahul takes a loan of Rs 150000 at an interest rate of 20% compound interest, which is compounded annually. He agrees to pay three equal instalments in three years, one instalment at the end of every year. Find the value of each instalment.

[CAT Question Paper - sample paper]

  1. Rs. 71209 (Correct answer)

Solution:

P = 150000, n = 3, r = 20

Let X be the value of the instalment each year.

Using,

P (1 + r/100)n = X (1 + r/100)n-1 + X (1 + r/100)n-2 + X (1 + r/100)n-3+….+ X (1 + r/100)

⇒ 150000(1 + 20/100)3 = X (1 + 20/100)3-1 + X (1 + 20/100)3-2 + X (1 + 20/100)3-3

⇒ 150000(216/125) = X (36/25) + X(6/5) + X

⇒ 150000(216/125) = X (91/25)

∴ X = 71209

Hence, the correct answer is Rs. 71209.

Question 3: What is the amount (in INR) of debt that will be discharged in 6 equal instalments of INR 800 each, if the debt is due in 6 years at 5% per annum?

[CAT Question Paper - sample paper]

  1. Rs. 6600

  2. Rs. 7500

  3. Rs. 8000

  4. Rs. 5400 (Correct answer)

Solution:

Given:

Installment = INR 800

Rate, r = 5%

Time, t = 6 years

Let the debt be x.

Instalment = (Debt × 100) / [100t + {r × t(t-1)} / 2]

⇒ 800 = 100x / [100 × 6 + {5 × 6(6-1)}/2]

⇒ 800 = 100x / 675

∴ x = 5400

Hence, the correct answer is Rs. 5400.

Logical Reasoning And Data Interpretation:

Ranking (LR)

Ranking is the process of determining the position or place of a person or thing based on comparison and other information given in the questions for the CAT exam.

It is one of the most important parts of Logical Reasoning for the CAT exam.

For some information about this topic, students can study “Ranking logical reasoning pdf”, “order and ranking Logical Reasoning ” and “Ranking logical reasoning questions”.

Ranking: Questions Type Asked In CAT Exam

There are many different types of questions asked in the CAT exam based on ranking.

Some of them are:

  1. The position/Ranking of the person is asked from the bottom/left/right/top.

  2. Questions based on swapping of positions.

  3. Questions are based on the number of persons between two positions.

  4. Questions based on finding the total number of objects or persons.

Approaches And Tips To Solve The CAT Question Paper On Ranking

  1. A total number of persons in a row = (sum of positions of the same person from both sides) – 1
    Example: Sunil is 16th from either end of a row; the total number of persons in the row = 16 + 16 - 1 = 31

  2. If the position of a person/ object from one end is n, and the total number of persons/objects in the row is m; then the position of the same person from the other end will be (m - n + 1).

  3. While calculating the number of places between two persons, cases of overlapping and non-overlapping should be treated differently.

  4. Analyse the given information in the question by thorough reading.

  5. Use visualisation/imagination skills.

  6. Try to draw all the possibilities and eliminate the wrong one.

Questions On Ranking (LR) From CAT Previous Year Papers

These questions can help you build the concept of ranking: (Based on the CAT exam):

Question 1. In a queue, Antara is 19th from the front while Manthara is 28th from behind and Lolita is just in the middle of the two. Consider that there are 50 people in the queue. What position does Lolita occupy from the front? [CAT sample paper]

  1. 20th

  2. 19th

  3. 18th

  4. 21st (Correct answer)

Solution:

Total persons sitting between Antara and Manthara = 50 – 19 – 28 = 3

Lolita is in the middle of the two; So, Antara and Lolita have just 1 person between them. Therefore, Lolita must be at 21st from the front.

Question 2. In a row of boys, Ritesh and Manish occupy the 7th place from the right end and 9th place from the left end, respectively. Now if they interchange their places, Ritesh and Manish occupy 25th place from the right and 27th place from the left, respectively. How many boys are present in the row?

  1. 35

  2. 26

  3. 33 (Correct answer)

  4. Cannot be determined

Solution:

Ritesh's Position from the right end = 7; Now Manish occupies the position of Ritesh which is 27th from the left.

So, total number of boys = 7 + 27 – 1 = 33

Question 3: Five friends, A, B, C, D, and E, are sitting in a row facing north. A is to the immediate right of B and immediate left of C. D is to the immediate right of E and immediate left of B. Who is sitting in the middle?

  1. A

  2. B

  3. C

  4. D

Solution:

From the given conditions:

  • A is immediately right of B → B, A, C (because A is immediately left of C)

  • D is immediately right of E and immediately left of B → E, D, B, A, C.

Therefore, B is in the middle.

Question 4: In a class of 40 students, there are 10 boys and 30 girls. Ramesh is ranked 12th when students are arranged in descending order of marks. Among the boys, he is ranked 7th. How many girls are ranked above him?

  1. 4

  2. 5

  3. 6

  4. 7

Solution:

Ramesh is ranked 12th overall, and 7th among the boys.

So, there are 6 boys ranked higher than him.

Therefore, the number of girls ranked above him is 11 - 6 = 5

Prerequisite For CAT Preparation:

To Prepare the questions based on Ranking for CAT 2024, a student must know of:

  • Basic Additions and subtractions

  • Sequence and Series

VARC Topic: -Tenses Part-2 (Past Tense)

As discussed in the previous article, tenses are divided into three types for easy CAT preparation. Today we are going to discuss, Past Tense.

Past tense is used to describe the event that has occurred in the Past.

Past Tense can further be divided into four categories to indicate the action as follows:

  • Simple Past Tense/ Past Indefinite Tenses: A habitual action in the past. The action has already finished in the past but the time of action is not definite.
    Formula: Subject + Verb (Past tense) + Object
    Example: Geetha studied at IIM Ahmedabad.

  • Past Perfect Tense: It refers to an action that happened before another event.
    Formula: Subject + Had + Verb (Past participle) + Object
    Example: Kushal noticed that Barsha had left his mobile behind.

  • Past Continuous Tense: Continuous action in the past, that happened for some time.
    Formula: Subject + Was/ Were + Verb (Present participle) + Object
    Example: Sneha was eating pizza.

  • Past Perfect Continuous Tense: denotes an action that was in progress before another event in the past.
    Formula: Subject + Had been + Verb (Present participle) + Object
    Example: I had been preparing for this examination for five months.

Students can practice on simple past tense worksheets and read simple past tense formulas to get more grasp on the basic past tense examples.

CAT questions on Past tense and Past participle from Previous year's papers

Question 1. I met the director yesterday, and he assured me that he will help if you will ask him. [Sentence correction]

[CAT previous year papers]

  1. have met the director yesterday, and he assured me that he will help if you ask him.

  2. met the director yesterday, and he assured me that he would help if you asked him.

  3. met the director yesterday, and he assured me that he would help if you asked him.

  4. No correction required

Solution:
The correct answer is Option B.

With ‘yesterday’, the Past indefinite tense should be used. So, option A is incorrect.

Option (c) is wrong because in “he will help if you will ask him”, the verb 'will help' is in the future, which is the result of a condition ‘if you will ask’ and both cannot be in the future.

Question 2. The Chief Proctor______into the classroom to see what the students_________. [Fill in the blanks]

  1. Go, had been doing

  2. Went, was doing

  3. Gone, had been doing

  4. Went, were doing

Solution:

The correct answer is option D.

Past indefinite with past continuous tense (For progressive work) is to be used.

Option A is wrong because “The chief proctor” is singular. So “goes” is appropriate or the past form.

Option B is wrong because “students” is plural, so “were doing” should be appropriate.

Option C is wrong because the past participle form of a verb alone can’t be used. There has to be a has/have/had.

Prerequisite For Tenses:

  • Basic Knowledge of Verbs and their forms.

  • Knowledge of the use of helping verbs (Was/Were/had/had been)

  • Knowledge of Nouns/Pronouns.

Tips For Error Correction In Past Tenses:

  • Learn the rules of all types of past tenses.

  • Read good Newspapers which use correct grammar (like The Hindu).

  • Do basic exercises on Past tense.

  • Attempt Mock-Tests.

Two friends Moloy and Niloy passed out from the Purulia Institute of Science and Technology with B.Tech degrees in Mechanical Engineering, but even after a year placement was hard to find. So they decided to take the challenge head-on, came down to Kolkata, rented a garage space on Park Street, and having an affinity towards making people enjoy good food, started their firm named 'B.Tech Bread-Omlette Wala'. 

They started with three items on the menu. One was the French Toast which could be prepared in 3 minutes. The second was the Egg Tortillas which took 15 minutes to prepare. Any one of Moloy and Niloy could prepare any one of them at a time. The third was the Egg Bhurji with French Fries. This however was prepared on an automated fryer which could prepare 3 servings at a time and took 5 minutes irrespective of the number of servings equal to or below 3. The fryer did not need anyone to attend to it, and the time to put in the raw ingredients could be neglected. So one could tend to the preparation of other items while the Egg Bhurji with French Fries were being prepared. 

They wanted to serve the orders as early as possible after the order was given. The individual items in any order were served as and when all the items were ready, and the order was then considered closed. None of the items on the menu were prepared in advance in anticipation of future orders.
