Question

The present age of Rahul is thrice that of Shivam. Eight years from now,
Rahul's age will be one more than twice the age of Shivam. Find the age of
Rahul before 8 years from the present.
(A) 20 years (B) 26 years (C) 19 years . (D) 17 years
(E) None of these​

Answer 1

Answer:

Step-by-step explanation:

Let the present age of Shivam be x.

Then the present age of Rahul is 3x.

After eight years,

Shivam's age = x+8

Rahul's age= 1+2(x+8)

                 or 3x+8

By question,

 1+2(x+8) = 3x+8

 1+2x+16  = 3x+8

 17+2x      = 3x+8

 17 - 8       = 3x - 2x

    9           = x

Therefore x=9

So,

Rahul's present age = 3x

                                   = 3 *9

                                   = 27 years

Before eight years from present Rahul's age = 27 - 8

                                                                             = 19 years

(C) 19 years

Hope it helps.
