Answer 1

Answer:

10000

Step-by-step explanation:

Let us assume that his income is 100

1) 60% of his income in household expenses

=100*0.4

=40.

2) 20% of the remainder on recreation

=40*0.8

=32

3) 20% of the remainder on petrol

=32*0.8

= 25.6

Now given that he saves 2560 per month

=(2560*100)/25.6

=10000

Therefore his income is 10000
