Answer:

Present age of Ravi is 5 years.

Step-by-step explanation:

Given :-

• 15 years from now Ravi's age will be 4 times than his present age.

To find :-

• Ravi's present age.

Solution :-

Let the present age of Ravi be x years.

After 15 years,

• Age of Ravi = (x+15) years

★ 15 years from now Ravi's age will be 4 times than his present age.

According to the question:-

x+15 = 4x

→ x-4x = -15

→ -3x = -15

→ x = -15/-3

→ x = 5

Therefore, the present age of Ravi is 5 years.

Verification :-

• Present age of Ravi = 5 years

After 15 years,

Ravi's age will be = (5+15) = 20 years

According to the question ,

Ravi's age (after 15 years) = 4× Ravi's present age

→ 20 = 4×5

→ 20 = 20

Hence Verified !
