If the number of Model-A mobile phones produced by the company in 2022 was the same as that in 2021, then what would have been its approximate percentage share in the total production of 2022?
A11%
B13% ✓ Correct
C15%
D9%
Correct answer: (B) 13%
Explanation
The share would have been about 13%, so the answer is 13%.
Model-A phones in 2021 are 15% of 4,50,000, which is 67,500.
The total production in 2022 is 5,20,000.
The share is 67,500 divided by 5,20,000 times 100.
This works out to about 12.98%, which rounds to 13%.
The base for a share is the total production of the year in question, here 2022.
Using the 2021 total or the actual 2022 Model-A count would give the wrong share.
