Question

The sum of three consecutive multiple of 5 is 555. find the number

Answer 1

180,185,190 are the three consecutive multiples of 5 whose sum is 555

Answer 2

Let the three consecutive multiples of 5 be x, x+5 and x+10 respectively
According to the question
x+x+5+x+10 = 555
3x +15 =555
3x = 555-15
3x = 540
x =540/3
x = 180
=> x= 180
=> x+5 = 180 +5 = 185
=> x+10 =180 + 10 = 190
Therefore, The three consecutive multiples of 5 are 180,185 and 190 whose sum is 555
