Question

729 ml of a mixture contains milk and water in the ratio 7:2. How much more water is to be added to get a new mixture containing milk and water in the ratio 7:4

Answer 1

Let the common multiple of the ratio be “x”

Therefore, according to given condition,

7x + 2x = 729

Therefore,

9x = 729

i.e x = 81.

Therefore, 2x = 162 ml

In the new mixture, amount of water should be 3x

i.e 243ml

Therefore amount of water to be added is, “x” ml

Therefore, 81ml of water must be added to the current mixture.
