Correct Answer: 79/69
Solution : Given:
2/3 : 19/29 :: 8/7 : ?
In the given sequence, 2/3 corresponds to 19/29. This relationship can be expressed as 2/3 is to (2 × 10 - 1) / (3 × 10 - 1)
Similarly, when we apply this same logic to the next pair i.e. 8/7, we get (8 × 10 - 1) / (7 × 10 - 1) = 79/69
Hence, third option is correct.
