A workshop makes 200 parts a day. Output grows by 10% in one month and by another 10% the next month. Enter the final number of parts per day.

242
Explication
Apply each rise to the updated output: 200 × 1.10 × 1.10 = 242. Adding the two rates would give a 20% rise and 240 parts, missing the extra growth on the first increase.
