Question 9

Mr Giridhar spends 50% of his monthly income on household items and out of the remaining he spends 50% on transport, 25% on entertainment, 10% on sports and the remaining amount of Rs. 900 is saved. What is Mr Giridhar's monthly income?

Solution

Let the total monthly income of Mr Giridhar be 100g

The proportion of income he spends on household items = 50% i.e 50g

Of the remaining 50%, the proportion of income he spends on transport, entertainment and sports are 50%, 25%, 10%

15% of 50g = Amount saved

7.5g = 900(given)

100g = 12000

The monthly income of Mr Giridhar = Rs.12000
