Question

a person spend 10% of his total income 25% on food 5% on education of his children and 75% on other expense .if he have 9000at the end of the year which is the monthly income​

Answer 1

Explanation:

Let's assume income of X to be 100.

If X spends 20% on house rent, he will be left with 100*.8 = 80

Now out of 80 he spends 70%, so now he is left with 80*.3 = 24

Here 24 represents saved income of $1800 , then 100% represents 1800*100/24=7500.

So the total income is 7500.
