Question

The sum of three consecutive multiples of 5 is 555. Find the multiples.

Answer 1

let the three consecutive multiples of 5 be x,x+5,x+10
then x+x+5+x+10=555
3x+15=555
3x=540
x=180
thus , the no.s are 180, 185 ,190

Answer 2

Let the three consecutive multiples of 5 be 5x, 5x + 5 and 5x + 10

The sum of three consecutive multiples of 5 is 555.

5x + 5x+5 + 5x+10 = 555

15x + 15 = 555

15(x+1) = 555

x+1 = 555/15

x+1 = 37

x = 37-1

x = 36

5x = 5(36) = 180

5x+5 = 180 + 5 = 185

5x+10 = 180+10 = 190

Therefore, The three consecutive multiples of 5 are 180,185 and 190.
