Answer 1

Answer:

33 years is the answer part a

Answer 2

Answer:

(a) 33 years

Step-by-step explanation:

Assume that the present age of father be x years and son be y years.

The present age of a father is 3 years more than three times the age of his son.

→ x = 3y + 3 ...................(1)

Three years later, father's age will be 10 year than twice the age of the son.

3 years later:

• Age of father = (x + 3) years
• Age of son = (y + 3) years

As per given condition,

→ x + 3 = 2(y + 3) + 10

→ 3y + 3 + 3 = 2y + 6 + 10 [From (1)]

→ 3y + 6 = 2y + 16

→ y = 10

Substitute value of y in (1)

→ x = 3(10) + 3

→ x = 33

Hence, the present age of father is 33 years and son is 10 years.
