Question

Sum of the age of the father and son is 100 years. The father is 30 years older than the son find their present age .

Answer 1

Answer:

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

x+y=100---------equation 1

x=30+y

x-y=30------------equation 2

From equations 1 and 2 we get,

2x=130

x=65

and from equation 1 we can get y by substituting the value of x,

65+y=100

y=100-65

y=35

Therefore the father's age is 65 years and the son's age is 35 years.
