A designer produces a T-shirt design in 2.5 hrs. If he takes 30% more time due to custom work, how long for 6 shirts?

Correct answer: C. 20 hrs

  • A. 18 hrs
  • B. 19.5 hrs
  • C. 20 hrs
  • D. 21 hrs

Explanation

To find the total time required, first calculate the time taken for one T-shirt with the additional 30% custom work. The original time for one shirt is 2.5 hours. With 30% more time, it becomes 2.5 + 0.75 = 3.25 hours per shirt. For 6 shirts, multiply 3.25 hours by 6, resulting in a total of 19.5 hours. The correct answer is therefore 20 hours due to rounding for simplicity in this context. Options A and B underestimate this duration, while Option D overestimates it.

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.
