(1) 2 years ago,
Piya’s age = x years
∴ Om’s age = 2x years
∴ Om’s present age
= (2x + 2) years
Piya’s present age
= (x + 2) years
According to the question,

2x+2+4

x+2+3

=

9

5

⇒

2x+6

x+5

=

9

5

⇒10x+30=9x+45
⇒10x−9x=45−30
⇒x=15
∴ Om’s present age
= (2x + 2) years
= (2 × 15 + 2) years
= 32 years
