Statement I: It is given that the ratio of son's age to father's age is 1:5 Let the son's age be x and father's age be 5x. (x)(5x)=245 x=7 Therefore, son's age is 7 years and father's age is 35 years. After 9 years, son's age is 16 years and father's age is 44 years. Ratio =16:44=4:11 Statement II: Initially - 70L milk and 30L water After selling 1∕5 th of the solution −56L milk and 24L water Adding water −56L milk and 44L water water:milk =44:56=11:14 The answer is option B.
