Answer 1

Answer :

The Monthly Income of Mr. Moti lal is 7875 Rs.

Step-by-step Explanation :

Given : 1) Moti Lal spends 20% on house rent and 60% on other household

expenses of his monthly income.

2) And saves 2520 rupees

To find : monthly income = ?

Let the monthly income be X

Then 20% of monthly income be = 20X/100 = X/5

Then the rest = X - 20X/100 = 80X/100 = 4X/5

Then 60% of rest = (60/100) x (4X/5) = 240X/500 = 120X/250 = 12X/25

Saves = 2520 rupees

Total expenses = (X/5) + 12X/25 = 85X/ 125 = 17X/25

Then according to the question,

X - (17X/25) = 2520

8X/25 = 2520

8X = 63000

X = 7875 Rs

Hence his monthly income is 7875 rupees
