The present age of Sumit is 1/8th of his father. After 8 years, the father‘s age will be twice the age of Raman. If Raman celebrated his 6th birthday six years ago, what is Sumit’s present age?

Raman celebrated his 6th birthday 6 years ago, so Raman's present age = 6 + 6 = 12 years. After 8 years, Raman's age = 12 + 8 = 20 years. After 8 years, father's age will be twice Raman's age, so father's age after 8 years = 2 × 20 = 40 years. Therefore, father's present age = 40 - 8 = 32 years. Sumit's present age = 1/8 × father's present age = 1/8 × 32 = 4 years.
