A 280 ml mixture is composed of milk and water in the ratio 11:9. If an equal amount 'x' ml of both milk and water is added, the new ratio of milk to water changes to 9:8. Determine the value of 'x'.
Quantity of milk in 280 ml of mixture = 11/20 × 280 = 154 ml Quantity of water in 280 ml of mixture = 280 – 154 = 126 ml So, (154 + x)/(126 + x) = 9/8 Or, 1232 + 8x = 1134 + 9x Or, x = 98
