Detailed Solution

It rained 2 days for every 6 days

In total, it rained for 6days

Taking the weekly rained days = 2/6

Total rainy days = 6

2/6 = 6/X (X = how many days Ria spent in Delhi)

Then, transferring 6 on the right side to the left side

It will become – > 

2/36 = 1/X

1/18 = 1/X

Which means -> X=18

Ria stayed in Delhi for 18 days.

Hence, option C is the correct Answer.
