Answer 2

Step-by-step explanation:

Let the age of Nazism be x then his son be y

eight years ago age

Nazism= x-8

Son= y-8

According to question,

x - 8 = 3(y-8)

or, x - 8 = 3y - 24

or, x-3y = -16----------(I)

x + y = 56-----------(ii) ----Given

subtract eq(i) from (ii)

X + Y = 56

X - 3Y = -16

4Y=72

Y = 18yrs

Put the value of y = 18yrs in equation (I)

X + Y = 56 yrs

or, X + 18yrs= 56 yrs

or, X = (56-18) yrs

= 38 yrs

Hence,

Son is 18 yrs old now.
