Question

three consecutive integers are such that when they are taken in increasing order and multiplied by 3,4,5 they add up to 386. find these numbers

Answer 1

let the integers are x, x+1 , x+2

multiplied by 3x , 4(x+1), 5(x+2)

added,

3x + 4x + 4 + 5x + 10 = 386

12x + 14 = 386

12x = 372

x = 372/12

x = 31

numbers are 31, 32, 33
