The product of two consecutive positive multiples of 5 is 750. What is the smaller of the two numbers?
Show answer & explanation
Correct answer: D
Explanation
Given:
Two consecutive multiples of 5; Product = 750
According to the formula:
The numbers are 5n and 5(n+1)
5n × 5(n+1) = 750
25n(n+1) = 750
n(n+1) = 30
n = 5
The numbers are 25 and 30
25 is the smaller number.
