Question

and what is his Income?​

Answer 1

1272

Step-by-step explanation:

Let his monthly income be Rs. 100

His expenditure is Rs. 78.

Therefore, his savings is 100 - 78 = Rs.22

Let us put this in reverse way. If the savings is Rs. 22, then the income is Rs. 100.

Then the income is Rs. 100/2

If the income is Rs. 280 then the income is 100/22 x 280 = 1272

Hence his monthly income is Rs. 1272
