Question

33. Sum of the ages of a father and a son is 60 years. Mother is 20 years elder than her son. Find the average age of
father and mother​

Answer 1

Answer:

40

Step-by-step explanation:

Let the father's and son's age be x and you respectively

therefore x + y = 60

or, y = 60-x ...... eq (1)

Again, Mothers age = 20+x .... eq(2)

from eq 1&3

we get -----

x+20+60-x/2 = 40
