Percentage Topic Question 1 (RBI Grade B 2022 Exam)
Maya’s monthly salary is 60% more than that of Swevi. Both Swevi and Maya, out of their respective monthly salary, pay an equal sum towards EMI. Out of the remaining monthly salary, Maya and Swevi, spend a certain amount towards house rent. The amount that Swevi pays towards EMI is 20% of her monthly salary.

II: The difference between house rents paid by Maya and Swevi is Rs 10000. The house rent paid by Maya is Rs 6000 more than the EMI paid by her. If the house rent paid by Swevi is 33.33% of the EMI paid by Maya, the salary of Maya is?
A. Rs. 30000, Rs. 36000
B. Rs. 45000, Rs. 60000
C. Rs. 120000, Rs. 48000
D. Rs. 75000, Rs. 48000
E. Rs. 135000, Rs. 60000
Answer and Explanation
The first thing you need to do is read the question carefully. Here are the observations:
- There are two people, Maya and Swevi.
- Maya’s salary is 60% more than that of Swevi.
- Let’s assume Swevi’s salary is 500a. And Maya’s salary is 60% more i.e. (50%+10%) of 500a + 500a
- Maya’s salary will be (250a + 50a) + 300a = 800a
- Both Maya and Swevi are paying an equal amount in EMI.
- Swevi’s EMI is 20% of her monthly salary.
- Swevi’s EMI is 20% of 500a = 100a
- Maya’s EMI is also = 100 a
- Maya’s house rent is x times of her EMI i.e. 100ax
After understanding the question, let’s dive into the statements:
Statement 1: Find the total savings of Maya if her expenditure on EMI and house rent is just half of her total salary.
EMI + House Rent = Salary/2
100a + 100ax = 400a
100ax = 300a
100a * x = 100a * 3
X = 3
EMI expenses of Swevi is 30,000, meaning 100a = 30,000
a = 300
EMI and house arent are the only expenses.
Maya’s income is 800 a. So, the value would be 800*300 = 240,000
Maya’s EMI is 100a or 30,000
Maya’s House Rent is 100ax = 100a*3 or 30,000*3 = 90,000
Maya’s total expenses = 90,000+30,000 = 120,000
Maya’s total savings would be: Income – Expenses i.e. 240,000 – 120,000 = 120,000
If you look at the options given in the answers, there’s only one option which includes the value of 120,000. This means you need not solve the 2nd statement, saving you a lot of time.

Percentage Topic Question 2 (RBI Grade B 2021)
Study the following information carefully and answer the given questions. The table below shows the cost price and selling price of 5 different articles sold by a shopkeeper:
Note: Total cost price of article = Cost price + Cost of transportation
Q) If the cost price of article S is 20% more than the cost price of Article T then find the selling price of article S?
A. Rs. 2050
B. Rs. 4450
C. Rs. 8888
D. Rs. 9000
E. Rs. 5000
Answer and Explanation
Make sure to read the question carefully. Based on the available information:
The cost price of article T is: 8000
The cost price of article S is: 8000*120% = 9600
We need to calculate the selling price of article S.
The cost of transport for S is: 500
Total Cost Price will be 9600 + 500 = 10100
As there is a loss of 12%, the Selling Price will be: 88% of 10100 = 8888
Answer: C
Percentage Topic Question 3 (RBI Grade B 2019)
A number when multiplied by 7 gives another number that is as much above 260 as the original number itself is below 260. What is 32% of the original number?
A. 16
B. 18.5
C. 20.8
D. 17.5
E. None of these
Answer and Explanation
Let’s assume that our number is: x
When multiplied by seven gives as much another number which is as much above 260 as the original number itself is below 260. According to this statement:
7x – 260 = 260 – x
8x = 260+260
8x = 520
x = 520/8
x = 65
Calculating 32% of x or 65
32% is also 30% + 2%
30% is also 3*10% (3*6.5)
2% is also 2*1% (2*0.65)
So, 32% of 65 is = 19.5+1.3
C = 20.8

A. 1930
B. 1500

Answer and Explanation
Let’s assume Bina’s income is: Rs. 100
Bina invest 10% of her income in stocks i.e. Rs 10
Bina spends 15% of the remaining on groceries i.e. 90*15//100 = 13.5
Bina is left with = 76.5 (90-13.5)
Bina gives the remaining to her husband: 30600
The difference between the amount spent on groceries and the investment in stocks = 13.5-10 = 3.5
76.5 = 30600
Difference is 3.5
1 = 30600/76.5*3.5
The difference will be: 1400
Answer is E: 1400
Percentage Topic Question 5 (RBI Grade B 2019)
The wages of a laborer are increased by 15% and his working hours are also increased by 9%. Initially, he used to earn Rs. 18, 000 per month for 300 hours in a month. Find his total earnings in a month now?
A. Rs. 21,000Â
B. Rs. 22,563
C. Rs. 23,623
D. Rs. 24,868
E. Rs. 23,456
Answer and Explanation
After reading the question carefully, we can say:
Total working hours: 300
Total earning: Rs. 18,000
Earning per hour: 18000/300 = Rs. 60
As wages are increased by 15%, now the laborer is making:
60 + 60 * 15/100 = Rs. 69 per hour
Also, the working hours increased by 9%. New working hours will be =
300 + 300*9/100 = 327 hours
Total earning per month = 327*69 = Rs. 22,563
