A ferry takes 40 minutes to cross a river. If current slows it down by 25%, time taken increases to:
Correct answer: A. 50 min
- A. 50 min
- B. 52 min
- C. 55 min
- D. 60 min
Explanation
The ferry initially takes 40 minutes to cross the river. When the ferry's speed is reduced by 25% due to the current, the time taken increases by 25%. Calculating 25% of 40 minutes gives us an additional 10 minutes. Therefore, the total time taken is 40 + 10 = 50 minutes, making Option A the correct answer. Options B, C, and D incorrectly estimate the effect of the current, adding more time than the actual increase.

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.
