Question

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

Let total capacity be x litres

According to question,

3x/4 - 15 = 7x/12

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

=> 3x - 60 = 7x /3

=> 9x - 180 = 7x

=> 2x = 180

Therefore, x = 90 litres

So, the capacity of drum is 90 litres.
