Answer 2

Rahul's monthly income is 39682.53.

Given:

income spent on rent = 10%

income spent on food = 20% of the remaining income

income spent on children's education = 30% of the income left

money saved = Rs. 20,000

To Find:

Rahul's monthly income

Solution:

let Rahul's monthly income be x

⇒ rent = 0.1x

income left = x - 0.1x = 0.9x

so, the amount spent on food = 0.9x × 0.2 = 0.18x

income left = 0.9x - 0.18x = 0.72x

amount spent on children's education = 0.72x × 0.3 = 0.216

income left = 0.72x - 0.216x = 0.504x

⇒ 0.504x = 20,000

x = 20,000/0.504

x = 39682.53

Thus, Rahul's monthly income is 39682.53.
