What is the difference between the number of Model-C mobile phones produced by the company in the years 2021 and 2022?
The difference is 5,000 phones, so the answer is 5,000.
Model-C phones in 2021 are 30% of 4,50,000, which is 1,35,000.
Model-C phones in 2022 are 25% of 5,20,000, which is 1,30,000.
The difference is 1,35,000 minus 1,30,000, which is 5,000.
A larger percentage on a smaller base can still exceed a smaller percentage on a larger base.
Here the 2021 count is slightly higher despite the lower total production that year.
