B) 120 g
Description for Correct answer:
The existing solution contains 40% sugar and
here sugar has to be mixed.
Therefore, the other solution has 100% sugar
According to the rule of allegation,
Required ratio = 50 : 10 = 5 : 1
The two mixtures should be added in the ratio of 5 : 1.
Therefore, Required sugar = 6005×16005×1 = 120 g
