Question

a drum kerosene oil is 3/4 full when 15 litres of oil is drawn from it it is 7 by 12 full find the total capacity of the drum

Answer 1

Answer:

90 litres

Step-by-step explanation:

Let the total capacity be x

ATQ

(3x/4)-15=(7x/12)

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

3x-60(12)=(7x)×4

36x-720=28x

36x-28x=720

8x=720

x=90

total capacity=90 litres

Answer 2

Answer:

here your answer.....

Step-by-step explanation:

let the total capacity of tank be x litres

atq

3x/4-15=7x/12

3x/4-7x/12=15

(9x-7x)/12=15

2x=15*12=180

x=180/2=90

therefore total capacity of tank is

90 litres
