Question

The age of ram is 8 year more than the age of sham. The sum of the both ages is 28 years, then the age of ram is?

Answer 1

Let age of Sham be x, so age of Ram is 8+x.

28=x+8+x
So, x=10

Age of Sham=10 and age of Ram=18

Answer 2

Let the age of sham be x and the age of ram be y
Therefore,
x + 8 = y
and,
x + y = 28
Therefore,
x + y = 28,
x + 8 = y
x - y = - 8
- (x + y = 28)
- 2y = - 36
y = 18
Therefore
x + y = 28
x + 18 = 28
x = 10
Therefore age of ram = 18 yrs
