Two men can do a work in 15 days. Their combined work/day is
Correct answer: D. 1/15
- A. 1/30
- B. 1/20
- C. 2/15
- D. 1/15
Explanation
The correct answer is 1/15. Since two men complete the work together in 15 days, their combined work rate per day is 1/15 of the total work. The other options are incorrect because they either suggest completing the work in more or fewer days than specified. A rate of 1/30 means 30 days, 1/20 means 20 days, and 2/15 suggests 7.5 days, none of which match the given 15 days.

About Logical Problems
Logical problems present several conditions about people, objects, events or choices and require their possible arrangements to be tested. They cover constraint-based reasoning, rankings, matching, grouping, scheduling and elimination, with attention to the difference between a complete solution and a possibility that merely satisfies one condition.
