Question

Two years ago, the sum of the ages of father,mother and their two daughter is 40 years, then the sum of their ages after 3 years will be
A) 46 B)50 C)60 D)40

Answer 1

60 ...... I think c is the correct one logically...

Answer 2

Answer: C) 60

let current sum of ages be S

total number of people = 4

total age gap in 2 years = 2 x 4 = 8 years

given, S - 8 = 40 => S = 48 years

total age gap in 3 years = 3 x 4 = 12 years

hence sum of their ages after 3 years = S + 12 => 48 + 12 = 60 years
