2. 70 years
3. 80 years

5. 68 years

Answer 1

Correct Answer - Option 1 : 77 years

GIVEN:

⇒ Sudhir : Mother = 1 : 5      ----(1)

⇒ Sudhir : Father = 1 : 10      ----(2)

CALCULATION:

Making common ratios

⇒ Sudhir : Mother : Father = 1x : 5x : 10x      ----(3)

Age of Mother four years after = 39 years.

Mother’s present age = 35 years.

⇒ 5x = 35 years

⇒ 1x = 7 years

Present age of Sudhir = 7 years.

Present age of Father = 70 years.

Sum of their present age = 77 years.
