Let Salil’s present age be x years. Then his mother’s age is 3x years. After 5 years, their ages total 70 years. Solving gives x equal to 15. Therefore, their present ages are 15 and 45 years.
The present age of Salil’s mother is three times Salil’s present age. After 5 years, their ages will add up to 70 years. Find their present ages.

Assume Salil’s present age is x years. Since his mother is three times his age, her present age is 3x years. After 5 years, Salil’s age will become x plus 5 and his mother’s age will become 3x plus 5. According to the question, their total age after 5 years will be 70 years. Therefore, x plus 5 plus 3x plus 5 equals 70. Solving gives x equal to 15. Hence, Salil is 15 years old and his mother is 45 years old.
