Question

Milk and water are in the ratio of 3:2 in a mixture of 70 liters. How much water should be added so that the
rate of milk and water become 2:3?
a. 20
b. 28
c. 35
d. 40
e. 50

Answer 1

C) 35

Milk in container earlier detected = (4/5)*45 = 36 L

Water in container earlier detected = (1/5)*45=9 L

Now required Milk: Water ratio = 3:2

Suppose we add x L of water in container, 36/ (9+x) = 3:2

Solving to get x=15 L

15 L of water required to make ratio 3:2

42/28 TO 42/63 so 63-28=35
