Question

Q. Sum of ages of father and son is 68 years After 8 years father will b thrice older than son .What is the present sons age ?​

Answer 1

Answer:

age of son = 13 years

age of father = 55 years

Step-by-step explanation:

Let the age of father and son be x and y

x + y = 68

x = 68 - y -------------- equation 1

given after 8 father (x) will be thrice older than y son :

x +8 = 3(y + 8)

68 - y + 8 = 3 ( y + 8)

76 - y = 3y + 24

-y - 3y = 24 - 76

-4y = - 52

y = 52/4

y = 13

age of son (y) = 13 years

age of father (x) = 68 - 13 = 55 years
