If A works 6 days, B works 8, and total done = 1. Work per day = ?
Correct answer: C. 1/10
- A. 1/14
- B. 1/12
- C. 1/10
- D. 1/8
Explanation
The correct answer is 1/10. To solve this, consider the total days worked by A and B together, which is 6 + 8 = 14 days. However, the problem asks for the average work done per day by both A and B combined. By calculating the average work rate of A and B, we find that they complete the work in a rate of 1/10 of the total work per day. Thus, 1/10 is the most accurate representation of their combined work rate. Option A (1/14) incorrectly assumes a simple division of total work over total days, Option B (1/12) does not accurately reflect their contributions, and Option D (1/8) overestimates the work rate.

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.
