Two numbers are in ratio 3 : 4 and their LCM is 240. The smallest such pair’s smaller number is:
- 45
- 48
- 60
- 180
Explanation
Let the two numbers be 3x and 4x.
LCM of 3x and 4x = LCM(3,4) × x = 12x
We’re given that:
12x = 240 ⇒ x = 20
So, the two numbers are:
3x = 60 and 4x = 80
Smaller number = 60
