Two mixtures (milk and water) 'A' and 'B' contain milk and
water in the ratio 2:3 and 1:2 respectively. If 30 ml from 'A' and 36 ml from 'B' are mixed, find the percentage of water in the new mixture.Solution
Water in 30 ml of A = 30 × (3/5) = 18 ml
Water in 36 ml of B = 36 × (2/3) = 24 ml
Total mixture = 30 + 36 = 66 ml
Required percentage = (18 + 24) ÷ 66 × 100 = 63.64%
