Question

The age of Rahul and joyti are in the ratio of 3 : 5.Five years from now, the ratio of their ages will be 2:3. find their present ages.

Answer 1

Hello !!!



Let the present age of Rahul and joyti be 3X and 5X.




After five years age of Rahul = ( 3X + 5 ) years



After five years age of joyti= ( 5X + 5 ) years



According to question,



3X + 5 : 5X + 5 = 2 : 3



3 ( 3X + 5 ) = 2 ( 5X + 5 )



9X + 15 = 10X + 10


10X - 9X = 15 - 10



X = 5 years


Present age of Rahul = 3X = 3 × 5 = 15 years


And,

Present age of joyti = 5X = 5 × 5 = 25 years.

Answer 2

Here is your answer

Suppose rahul and joyti present age are 3y and 5y.


a/q,

3y+5/5y+5 = 2/3
3(3y+5) = 2(5y+5)
9y+15 = 10y+10
10y-9y=5
y=5

Rahul age is 15 yrs and joyti age is 25 yrs.
