Question

a vessel contains 27 liters petrol and 15 liters kerosene. if 'x' liters of mixture is taken out from the vessel and replaced by kerosene, then the ratio of petrol and kerosene in the mixture become reversed. then, find the value of 'x'

Answer 1

Let the total capacity of vessel be x litres

Kerosene initially= 18x/100

Kerosene finally= 15x/100

Kerosene present in 8 liters of mixture= 18*8/100

18x/100 - 18*8/100 = 15x/100

3x = 144

x = 48 litres

Answer 2

Answer:

kerosene. if 'x' liters of mixture is taken out from the vessel and replaced by kerosene then the ratio of petrol and kerosene in the mixture become reversed. then, find the value of 'x'.
