Question

Sum of the ages of father and son is 40 yr. If father age is 3 times than of his son, then find their respective ages

Answer 1

Let the son's age be x

Then father's age will be 3x

So,

3x+x=40

4x=40

x=40/4

x=10 Years

The age of son is 10 years and father's age is 3x =30years.

Answer 2

Answer:

Step-by-step explanation:

Let age of father be x and age of son be y.

Therefore, x+y = 40 -(1)

X = 3y (given)

Therefore equation (1) : 3y +y = 40

: 4y= 40

Therefore y= 10

So, x = 30
