Three numbers are in the ratio 1 : 2 : 3 and their HCF is 12. The numbers are

1. 12, 24, 36
2. 5, 10, 15
3. 4, 8, 12
4. 10, 20, 30

Correct Option: A

Let the numbers are p , 2p and 3p .
Their H.C.F. = p = 12
∴ Numbers = p = 12, 2p = 2 × 12 = 24 and 3p = 3 × 12 = 36
Hence , Three numbers are 12 , 24 and 36 .
