Q. Two numbers are in the ratio 3 : 4. If their LCM is 240, the smaller of two number is
✅ Correct Answer: (C)
60
Explanation: Let, these two numbers be 3x and 4x then their LCM = 12x
Now, according to question,
12x = 240
Or, x = 20
Thus, the numbers are (3x = 3 × 20) = 60 and (4x = 4 × 20) = 80
Then smaller in this two is 60
Now, according to question,
12x = 240
Or, x = 20
Thus, the numbers are (3x = 3 × 20) = 60 and (4x = 4 × 20) = 80
Then smaller in this two is 60
