Suraj completes $$\frac1{12}$$​ of a work in nine days. At this rate, how many more days will he take to complete the work?

Correct option is D

Given:

Suraj completes $$\frac{1}{12}$$​ of the work in 9 days..

Solution:

If $$\frac{1}{12}$$​ work takes 9 days, then full work takes:

Total time = 9 × 12 = 108 days

Remaining days = 108 – 9 = 99 days
