Answer 2

Correct Question :

A man's age is 7 times then his son. In five years he will be four times as old as his son. Find the present age of man and son.

Answer:

Let the age of son be x years.

The age of the man now = 7x years

⚚ In 5 years,

• Age of son = x + 5 years
• Age of man = 7x + 5 years

☯ According to Question now,

➝ 7x + 5 = 4(x + 5)

➝ 7x + 5 = 4x + 20

Substracting 4x from both sides we get

➝ 3x + 5 = 20

Substracting 5 from both we get

➝ 3x = 15

Dividing both sides by 3 we get

➝ x = 5 years

Therefore,

• Present Age of son = x = 5 years
• Present Age of man = 7x = 7(5) = 35 years
