# If A: B = 5: 7 and B: C = 6: 11, then A: B: C =?

- 55 : 77 : 66
- 30 : 42 : 77
- 35 : 49 : 42
- None of these

**Answer: (2) 30: 42: 77**

**Explanation:-**

A: B = 5: 7 and B: C = 6: 11

Then, A: B: C = 5 x 6: 7 x 6: 7 x 11

= 30: 42: 77

So, the value of A: B: C is 30: 42: 77.

Hence, the correct answer is option (2) 30: 42: 77.
