Question

The sum of ages of 4 children born at the interval of 2 years is 52. what is the age of the oldest child

Answer 1

let the age of the smallest child be x
therefore, the age of the other children will be+
x+2, x+4, x+6 (given that each child is born at the interval of 2 years)
but the sum of all the years of children of equal to 52
=> x + (x+2) + (x+4) + (x+6) =52
= x+x+2+x+4+x+6= 52
= 4x + 12= 52
= 4x=40
= x=10= age of the smallest child
and hence the age of the oldest child= x+6
= 10+6 =16 years

Answer 2

Answer:

Step-by-step explanation:

let the age of the youngest child be y

so,the age of the following children. will be

y+2 , y+4 , y+6

Sum of their ages=48

According to question,

y+y+2+y+4+y+6=48

4y+12=48

4y=36

y=9

therefore,the age of eldest child=y+6

=9+6=15

Ans=15years
