A Jar contains 5x litres of the mixture of milk and water in the ratio of 3: 2 and 20 litres of the mixture is taken out. Then added 24 litres of the water in the remaining mixture, the ratio of the milk and water becomes 1: 2. Find the value of x?
A.15
B.10
C.20
D.30
E.None of these
Sol:
Milk in 20 litres = 3/5 * 20 = 12 litres
Water in 20 litres = 2/5 * 20 = 8 litres
(3x – 12)/(2x – 8 + 24) = 1/2
2x + 16 = 6x – 24
4x = 40
x = 10 litres
