Answer 2

Given:

Three consecutive multiples of 5 have the sum equal to 90.

To find:

To evaluate the multiples of five having a sum of 90.

Solution:

Let us take five consecutive multiples of five as

X, X+5, X+10

On adding the three multiples, the sum is 90

X+X+5+X+10 = 90

3X + 15 = 90

3X = 75

X = 25

Multiples are X, X+5, X+10.

By putting the value of X, we get the three multiples of five.

Multiples = 25, 25+5, 25+10

25, 30, and 35 are the three consecutive multiples of five.
