Let the present age of the Manan and Nitish be 6x and 7x Respectively.
- Manisha is 6 years older than Manan.
»Present age of Manisha be (6x + 6) yrs
→ (6x + 7x + 6x + 6)/3 = 40
→ (19x + 6)/3 = 40
→ (19x + 6) = 120
→ 19x = 120-6
→ 19x = 114
→ x = 114/19
→ x = 6
Hence,
The Present age of the Nitish will be 42 years.
