Question

The average age of the first three children in a class is 13.5 years. If the sum
of the ages of the first two children is 25 years, then what is the age of the third child ?​​

Answer 1

Answer:

let the ages of the children be x1,x2,x3,. then;

x1+x2+x3/3 = 13.5

x1+x2+x3 = 40.5

x1+x2 = 25

25+x3 = 40.5

x3 = 15.5

hence the age of third child is 15.5 years

that is 15years and six months.
