Question 1. Luaa spends her monthly salary in the following manner: 20% on house rent, 20% on food, 5 % on transportation, 10% on the education, and 20% on other household expenses. She saves the remaining amount of ₨. 5000 at the end of the month. Find out her monthly salary?

Options:

A. Rs. 35000

B. Rs. 25000

C. Rs. 20000

D. Rs. 30000

Solution:     Let the

Monthly Salary = 100%

Monthly Expenditure =

20% + 20% + 5% + 10% + 20% = 75%

Monthly Savings = 100% – 75% = 25%

Now, 25% of salary saved = 5000

Let’s take 100% salary as x

25% of x = 5000

x = 5000  × $\frac{100}{25}$

x = $\frac{500000}{25}$

x = 20000

Therefore, her monthly salary = Rs. 20000

Correct option: C

Question 2.Aman spends 60% of his income. Suppose his income is increased by 21% and his expenditure increases by 5%, then what is the increase in his savings (in percentage)?

Options:

A. 60%

B. 18%

C. 40%

D. 45%

Solution:     Let Aman’s income = 100

Expenditure = 60 and

Savings = 40 (We get 40 by subtracting, 100 – 60)

New Income is increased by 21% = 100 + 21 = 121

Expenditure Increased by 5% = 5% more than 60 = 105% of 60 = 63

New Savings = 121 – 63 = 58

Therefore, increase in savings = 58 – 40 = 18

Increase in % = $\frac{18}{40}$ × 100 = 45%

Correct option: D
