Question

the ratio of the ages of rai and joy is 4:9 . ten year hence the sum of their ages will be as 85 year. find the present ages of rai and joy.

Answer 1

joy's present age is 45

Answer 2

Let their present ages be 4x and 9x.

A/Q 4x+10 + 9x+10 = 85
=> 13x + 20 = 85
=> 13x = 85-20
=> 13x = 65
=> x = 65/13
=> x = 5

Therefore, present age of Rai is 4x=4*5=20years.
And present age of Joy is 9x=9*5=45years.
