Question

The sum of ages of father and his son is 75 years. If the ages of the son is 25 years less than the father's age. Find the age of the father?

Answer 1

Let the age of father be X
And age of aon be Y

X+Y = 75.........(1)
X-25 = Y ........(2)

Put the value of Y on equation 1

X+X-25 = 75
2X = 100
X = 50

Put the value of Y on equation 2
50-25 = Y
Y= 25.

Hope it helps.

Answer 2

Let the father's age be 'x' and son's age be 'y'..

then,, x+y = 75..

give that,, son's age is 25 years less than that of his father's ...

then,, x+x-25 = 75

= 2x - 25 = 75
= 2x = 75 + 25
= 2x = 100
x = 50 years...

therefore, age of the father is 50..
