Question

the sum of 3 consecutive multiples of 4 is 252, find them.

Answer 1

let the three consecutive numbers be x;x+4;x+8
according to question
x+x+4+x+8=252
3x+12 =252
3x =252-12
x =240÷3
x =80
req. numbers=x;x+4;x+8
=80;84;88 Ans.

Answer 2

let x be the first number of the consecutive numbers . So
the numbers will be:
x, x+4, x+8
=x+x+4+x+8=252
= 3x+12=252
3x=252-14
=240
x=240/3 which gives
x=80
so the consecutive numbers are: 80,80+4,80+8
= 80 , 84 , 88
