Question

A man spend 10% of his income on food and 80% of the remaining on clothing. If he still has RS 1800 find his income.

Answer 1

If his income was ₹ 100

food exp = 10

Bal =90

80% is(clothes bill)=72

He still has 90-72=18

=18% of income

and spending=100-18=72

or 72% of income

So if ₹1800 is final saved balance, his income was

1800/0.72

=(180000/72)

=10000/4

= ₹ 2500 ANSWER
