(#M40000841) TCS QUESTION tcs recent puzzle Keep an EYE

One grand father has 3 grand children two of the age difference is 3.Eldest child age is 3 times the youngest childs age and the eldest child age is two year more than the sum of other two children. Find what is the age of the elders child?
a)18 b)22 c)30 d)10

Solution

let the age of eldest child is E , that of elder child is M and that of youngest child is Y, then according to the given conditions
E = 3Y ....(1)
E = 2 + M + Y ....(2)
now third condition is somewhat complicated,
according to this condition 'two of the age difference is 3' so three cases will arise 1) E - M = 3, ......(3)
2) M - Y = 3, ......(4)
3) E - Y = 3, ......(5)
if we take first of the 3 conditions then on solving (1), (2) and (3) we will get E = 3, M = 0, Y = 1 which is wrong
now on solving (1), (2) and (4) we will get E = 15, M = 8, Y = 5
similarly on solving (1), (2) and (5) we will get E = 4.5, M = 1, Y = 1.5
only E = 15, M = 8, Y = 5 is correct so age of elder child is 8 years
