# If 2A=3B and 4B=5C, then C:A will be

**Answer: (3) 8: 15**

**Explanation:-
**2A = 3B and 4B = 5C

A/B = 3/2 and B/C = 5/4

Then, A: B = 3: 2 and B: C = 5: 4

A: B: C = 3x 5: 2x 5: 2 x 4

A: B: C = 15: 10: 8

A: C = 15: 8

Then, the ratio of C and A, C: A = 8: 15.

Hence, the answer is (3) 8: 15.
