Question

what is the age of father and his son if the sum of the age of a father and his son in years is 85 and thrice the difference of their ages in years is 75​

Answer 1

Step-by-step explanation:

Let father's age =x, son's age =y

As per question,

x+y=85⇒y=85−x ( 1)

3(x−y)=75

⇒3x−3y=75

⇒3x−3(85−x)=75 [ substituting value of y from equation (1) in equation (2) ]

⇒3x-255+3x=75

⇒x=55

So father's age =55 years
