Question

A man spend 3/8 of his monthly income on food and 2/5 of the remaining on clothes.
A) Find what fraction of his income is left with him?
b) If money left is rupees 1200; find his monthly income​

Answer 1

Answer:

a) 3/8

b)

Step-by-step explanation:

Let monthly income = x Rs

Money spent on food = x * 3/8

Remaining money post spent on food = x - 3x/8 = 5x/8

Money spent on clothes = 5x/8*2/5 = 2x/8

Remaining money = x - (3x/8+2x/8) = x - 5x/8 = 3x/8

So fraction of his income left with him = 3/8

b ) Money left = 1200

=> 3x/8 = 1200

=> 3x = 1200 * 8

=> x = 9600/3

=> x = 3200 Rs
