Question

Ram is twice as old as Reena five years ago, his age was three times Reena's age. Find their present age​.​

Answer 1

Step-by-step explanation:

3x-2x=15-5. x=10 years. ( Reena's present age). 2x=2*10=20 years ( Ram's present age).

Answer 2

Answer:

The present ages of Ram and Reena are 20 years and 10 years respectively.

Step-by-step-explanation:

Let the present age of Ram be x years.

And the present age of Reena be y years.

From the first condition,

x = 2y - - - ( 1 )

Now,

Age of Ram 5 years ago = ( x - 5 ) years

Age of Reena 5 years ago = ( y - 5 ) years

From the second condition,

( x - 5 ) = 3 ( y - 5 )

⇒ x - 5 = 3y - 15

⇒ 2y - 5 = 3y - 15 - - - [ From ( 1 ) ]

⇒ - 5 + 15 = 3y - 2y

⇒ 10 = y

⇒ y = 10 years

By substituting y = 10 in equation ( 1 ),

x = 2y - - - ( 1 )

⇒ x = 2 * 10

⇒ x = 20 years

∴ The present ages of Ram and Reena are 20 years and 10 years respectively.
