Question

A can do a work in 18 days. A and B both together can do the same work in 11 days. Then, in one day, B alone can do

• A. 13/198 part of the work
• B. 7/198 part of the work
• C. 15/198 part of the work
• D. 17/198 part of the work

Hint:

The shortcut for finding B's rate is: \[ \frac{\text{Difference in days}}{\text{Product of days}} = \frac{18 - 11}{18 \times 11} = \frac{7}{198} \]

Answer 1

The Correct Option is B
