Question

The sum of three consecutive multiple of 5 is 45. find the multiple

Answer 1

Answer: 10, 15 , 20

Here we go:

Step-by-step explanation:

Let the three consecutive multiples are x,x+5 and x+10

Now,according to question,

x+x+5+x+10=45

3x+15=45

3x=45-15

3x=30

x=30/3=10

one multiple=10

2nd multiple=10+5=15

3rd multiple=10+10=20

the smallest multiple=10

Technically you can just use your head and take 10,15,20
