​The H.C.F of three numbers is 15. If they are in the ratio 1 : 2 : 3, then find the numbers.​

Correct option is C

Given:

1:2:3 number of ratio

H.C.F of number 15

Solution:

H.C.F = 15

So number will be divided by 15 

Hence the number will be 

​$$1 \times 15 : 2\times 15 : 3 \times 15$$​​

= 15 : 30 : 45
