Question

The sum of three consecutive multiples of '5' is 45. What is the smallest of the three multiples

Answer 1

Answer:

Let 5x be the smallest multiple of 5.

Then, the three consecutive multiples shall be 5x, 5x+5 and 5x+10

According to the question,

5x+5x+5+5x+10=45

∴5x+5x+5x=45−15

∴15x=30

∴x=2

∴ Smallest multiple =5x=5×2=10
