# What was the Volume of Liquid in Jar Earlier?

A jar contains a mixture of two liquids A and B in the ratio 4:1. replaced with liquid B the ratio now becomes 2:3. The volume of liquid A present in the jar earlier was

- 20 litres
- 10 litres
- 16 litres
- 15 litres

**Answer: (3) 16 litres
Explanation:-
**The ratio of liquids A and B = 4: 1

Let be the quantity of Liquid A and B = 4X and X

According to the question,

{(4X – 10(4/5)} : {X – 10(1/5) + 10 } = 2: 3

= (4X – 8): (X – 2 + 10) = 2/3

= (4X – 8)/(X + 8) = 2/3

10 X = 40

X = 4

Therefore, the volume of liquid A = 4 x 4 = 16 litres.
