Three numbers are in ratio 1 : 2 : 3 and HCF is 12. The numbers are:
A. 12, 24, 36
B. 11, 22, 33
C. 12, 24, 32
D. 5, 10, 15
Answer: Option A
Solution(By Examveda Team)
Since, the numbers are given in the form of ratio that means their common factors have been cancelled. Each one's common factor is HCF. And here HCF = 12, hence, the numbers are 12, 24 and 36. Alternatively, Let the numbers be x, 2x and 3x. The HCF in x, 2x and 3x is x because 1, 2, 3 are prime. Hence, x = 12; then the other numbers are 24 and 36.Join The Discussion
