Let the present age of Nihal be x years.
∴ Age of sahil 7 years ago = x
∴ Present age of Sahil = x + 7
Now,
According to the question
(x + 7 - 5) + (x + 6) = 58
⟹ x + 7 - 5 + x + 6 = 58
⟹ 2x + 8 = 58
⟹ 2x = 50
⟹ x = 25 yrs
Ruchi = x + 7 + 4 = 25 + 11 = 36 yrs
∴ Ruchi's age after 10 yrs
= 36 + 10 = 46 yrs
