Question

The sum of three consecutive multiples of 5 is 3015. Find the first multiple numbe​

Answer 1

Answer:

Let the three consecutive multiples of 5 be 5x, 5(x+1) and 5(x+2).

According to the question,

5x+5(x+1)+5(x+2) = 3015

5(x+x+1+x+2)=3015

5(3x+3)=3015

3x+3=3015/5=603

3x=603-3=600

x=600/3=200
