Question

A man spends 2/5 of his salary on food, 3/10 of his salary on house rent and 1/8 of the salary on clothes. He still has Rs. 1,400 left with him. Find his salary.

Answer 1

Step-by-step explanation:

Let his salary be x then,

x - (2x/5 + 3x/10 + x/8) = 1400

=> 40x - (16x + 12x + 5x) = 56000

=> 40x - 33x = 56000

=> 7x = 56000

Hence, x = 56000/7 = 8000

Answer) Hence, his salary is 8000 rupees.
