Question

The present age of Ravi's father is four times the present age of Ravi. After 10 years the age of Ravi's father will be three times more than the age of Ravi. Find their present ages.

Answer 1

#answer#

Let the present age of Ravi be x

So,Present age of father=4x

Given that after 10 years

Ravi's ages will be= (x+10) years

So, Father's age =(4x+10) years

Also given that after 10 years the age of Ravi's father will be three times more than the age of Ravi.

Forming the equation according to the question

4x+10= 3(x+10) (balancing the age of Ravi)

4x+10= 3x+30

4x-3x= 30-10

x= 20

Hence Ravi's age is 20 years

Then father's age=4x = 4×20= 80 years.

Answer 2

Let the present age of ravi be x

then,

present age of Ravi's father be 4x

After 10 years,

ravi age =3( x + 10)

Ravi's father age = 4x + 10

A/q,

=> 3(x + 10) = 4x + 10

=> 3x + 30 = 4x + 10

=> 30-10 = 4x -3x

=> 20 = x

=> x = 20

present age of ravi is 20 years

present age of Ravi's father is = 4 × 20 = 80 years
