Question

1. A drum of kerosene oil is 3/4 full. When 15 litres of oil is drawn from it, it is 7/12 full. Find the total capacity of the drum.​

Answer 1

Step-by-step explanation:

let total capacity of drum = x

ATQ

3x/4 -15 = 7x/12

(3x - 60)/4 = 7x/12

12(3x - 60)=7x*4

36x - 720 = 28x

36x - 28x = 720

8x =720

x =720/8

=90 litre
