Question

39.
The average age of man and his son is 22 years. The ratio of their ages is 19:3 respectively. What is the man's age?​

Answer 1

Answer:

Let ,

man age=x

son age =y

(x+y)/2=22 ..eq1

and x/y= 19/3

x=19y/3       ..eq2

putting value of eq 2 in 1

19y/3 + y = 44

19y+3y=44 * 3

22y = 44 * 3

y = 6

putting this value in eq 1

x+6= 44

x= 38
