B Correct answer
Explanation

Veer's rate = 1/20, Ram's rate = 1/18. Combined rate = 1/20 + 1/18 = (9+10)/180 = 19/180. Work done in 5 days = 5 * 19/180 = 19/36. Work left = 1 - 19/36 = 17/36.

AI explanation

The combined one-day work of Veer and Ram is the sum of 1 divided by 20 and 1 divided by 18, which is 19 divided by 36. By multiplying this combined rate by 5 days, the work completed equals 95 divided by 36, or 19 divided by 18. Subtracting this completed portion from the total work of 1, the remaining work is 1 minus 19 divided by 18, resulting in 17 divided by 36.
