The ratio of two numbers is 2 : 3 and their Least Common Multiple is 60. What are the two numbers?
Show answer & explanation
Correct answer: C
Explanation
Given:
Ratio of two numbers = 2 : 3
Least Common Multiple (LCM) = 60
Let the numbers be 2x and 3x.
Since 2 and 3 are co-prime,
LCM = 6x
6x = 60
x = 10
Therefore, the numbers are: 2 × 10 = 20
= 3 × 10 = 30
