Question

Ram's age is three times his son's age. Ten years ago he was five times his son's age. What is Ram's presents age

Answer 1

Answer:

Ram present age=60 years

Given:

Ram is three times his son's age

Ten years ago he was five times his son's age

To find:

Ram's present age

Solution:-

Let ram's son age be x

Then ram age be 3x

10 years ago

Ram's son=x-10

And Ram=3x-10

According to the question

(3x-10)=5(x-10)

3x-10=5x-50

3x-5x=-50+10

-2x=-40

x=20

____________________

Ram's son age=20

And Ram's age=3x

=3×20

=60 year

Answer 2

Suppose the ram son age= x.

The age of ram = 3x

10 years ago he was five times his son age .

The age of ram son = x -10

The age of ram = 3x - 10

= ( 3x - 10) = 5( x - 10)

= 3x - 10 = 5x - 50

=3x - 5x = - 50 + 10

=-2x = -40

x = 20

The age of ram son = 20

The age of ram= 3x = 3 × 20 = 60.
