A mixture contains spirit and water in the ratio of 3 :

A mixture contains spirit and water in the ratio of 3 : 2. If it contains 3 litres more spirit than water, the quantity of spirit in the mixture is

Let the quantity of spirit in the mixture be x litres.
∴ Quantity of water
= (x – 3) litres
According to the question,

x	=	3
x − 3	=	2

⇒ 3x – 9 = 2x
⇒ 3x – 2x = 9
⇒ x = 9 litres
