Question

Answer

Given:
Bhanu spends 30% of his income on petrol on scooter.
He spends Rs.300 on petrol.

To find:
The expenditure on house rent.

Solution:
Let's assume Bhanu's income to be x.

Amount spent on petrol = 30% of x = 0.3x
Given, he spends Rs.300 on petrol.
Therefore, 0.3x = 300
x = 1000

Now, Bhanu spends 30% of his income on petrol, which is Rs.300. So, the remaining amount he has is:
1000 - 300 = 700

He spends 1/3 of the remaining amount on house rent.
Amount spent on house rent = 1/3 of 700 = Rs.233.33

But the options provided are in whole numbers. So, we need to round off the answer to the nearest whole number.
Rounding off 233.33 to the nearest whole number, we get Rs.233.

Therefore, the expenditure on house rent is Rs.233, which is option D.
