Question

Sunil is elder than Rajesh by 5 years. After 5 years their ages would be in the ratio of 5:4. Find their present ages.​​

Answer 1

Sunil 's age ==> x+5

By the given condition.

Five years after

Sunil's age =x+5+5=x+10

Rajesh' s age =x +5

\frac{x + 10}{x + 5} = \frac{5}{4}

x+5

x+10

=

4

5

4(x + 10) = 5(x + 5)4(x+10)=5(x+5)

4x + 40 = 5x + 254x+40=5x+25

40 - 25 = 5x - 4x40−25=5x−4x

15 = x15=x

so,we get,

x = 15x=15

The present age of Rajesh is 15yrs.

so,

Present age of Sunil= x+5 =15+5 =20

Therefore,

Their present ages are 15yrs & 20yrs .
