1. 1 / 3
2. 1 / 4
3. 1 / 5
4. 1 / 7

Show/Hide Answer

Answer = C - 1 / 5
Explanation: Suppose the vessel initially contains 8 litres of liquid. Let x littres of this liquid be replaced with water.
Quantity of water in new mixture = (3 - 3x/8 + x) litres.
Quantity of syrup in new mixture = (5 - 5x/8) litres.
(3 - 3x/8 + x) = (5 - 5x/8) = 5x + 24 = 40 - 5x
=› 10x = 16 =› x = 8/5
So, part of the mixture replaced = (8/5 x 1/8) = 1/5.
