CorrectNot quiteAnswer D

Correct answer: D

Explanation

  1. One tailor stitches 1208×5=3\frac{120}{8 \times 5} = 3 shirts a day.

  2. 10 tailors in 6 days: 3×10×6=1803 \times 10 \times 6 = 180 shirts.

Worth noting

150 shirts accounts only for the extra tailors, and 144 only for the extra day. Both changes increase the output.
