Question

the sum of the age of 4 children born at the intervals of 2 years each is 48 years. what was the age of the eldest child

Answer 1

Answer:

age of eldest child = 15 year

Step-by-step explanation:

let the age of younger child = x

then age of other child = (x+2) , (x+4), (x+6)

x + (x+2) + (x+4) + (x+6) = 48

x + x + 2 + x + 4 + x + 6 = 48

4x + 12 = 48

4x = 48 - 12

4x = 36

x = 36/4

x = 9

then age of four child is

x = 9

x + 2 = 9 + 2 = 11

x + 4 = 9 + 4 = 13

x + 6 = 9 + 4 = 15
