Question

11. Naveen's present age is three times of age of his son. After 5 years thedifference between the ages of both is 30. Find the present age of Naveen.​

Answer 1

Take Naveen son age x so his Naveen will 3x

Naveen son age= x
Naveen age= 3x
After five years, you have to add their age
Now we have to,

Naveen son age after five years= x+5
Naveen age after five years= 3x+5
The difference between their ages after 5 years is 30. So,

( 3x+5 ) - ( x+5 ) = 30
= 3x+5 - x-5 = 30
= 3x-x + 5-5 = 30
= 2x = 30
= x = 30/2
= x = 15
Naveen present age was 3x so,
= 3x
= 3*15
= 45 years
Naveen’s present age is 45 years.

Answer = 45 years
