Question

If the sum of the ages of a father and his son in
years is 65 and twice the difference of their ages in
vears is 50, then the age of the father is
(1) 45 years
(2) 40 years
(3) 50 years
(4) 55 years

​

Answer 1

Step-by-step explanation:

Let the age of father = x

& the age of his son = y

x + y = 65 --------(1)

2(x - y) = 50

x - y = 25 --------(2)

from equation (1) + (2)

2x = 90

x = 45

then y = 20

So , the age of father is 45 years
