One grandfather has three grandchildren, two of their age difference is 3, eldest child age is 3 times youngest childs age and eldest childs age is two times of sum of other two children. What is the age of eldest child?
option
(a) 5
(8) 10
(c) 8
(d) 15

Solution

Question data are wrong.
According to ours consideration

The 2nd condition given is wrong it should be two more than the age of other two children...

Let the three grandchildren age be a,b and c
Thus, a is youngest, c is eldest.
c = 3a.........(i)
c = 2+(a+b)..........(ii)
=> 3a = 2+a+b
=> 2a = 2+b
Thus, the ages are.....
a, 2a-2 , 3a.

Two of their difference is 3.
Thus, a- 2 =3 or a+2 =3 or 2a =3
a =5 or a =1 or a =3/2.

Thus ages are, 5,8,15
or , 1,0 3 (not possible). or 3/2, 1, 9/2 (not possible.).
The answer should be 15.

BJ  (13 years ago)

i think it is two more than the sum of other two
a-b=3 and b-c=3 then a-c=6
a=3c
if a=2+b+c
a=2+((2a/3)+3)
then go by options it is 15
