Question

sum of three consecutive multiples of 5 is 390, find the smallest multiple​

Answer 1

Answer:

125

Step-by-step explanation:

Let the three consecutive multiple of 5= x,x+5,x+10

Given that sum of three consecutive multiple of 5 is 390.

therefore,x+(x+5)+(x+10)=390

or,x+x+5+x+10=390

or,3x+15=390

or,3(x+5)=390

or,x+5=390/3

or,x=130-15

or, x=125

thus smallest multiple of 5=x=125
