Question

Q61. the sum of ages of 4 children born at the interval of 2 years is 52. what is the age of the oldest child? (a) 10 years (b) 12 years (c) 14 years (d) 16 years

Answer 1

let the age of children = x-4 , x-2 , x , x+2




ATQ



x-4 + x-2 + x + x+2 = 52




4x-4 = 52




4 ( x-1) = 52





x-1 = 13




x = 14




age of oldest child = x + 2
= 14+ 2
= 16
