Question

gauri spend 0.75 of her salary every month.if she ears rupees 12000 per month in how many months will she save rupees 39000?

Answer 1

We need to get the fraction which he saves.

Since we are working with fractions the monthly salary is taken as 1.

Savings = salary - expenditure

Savings = 1 - 0.75 = 0.25

This means savings is 0.25 of the salary.

Savings = 0.25 × 12000 = 3000

This is the monthly savings.

If he saves 39000, the time taken will be :

39000/3000 = 13 months
