The percentage of 4AH batteries sold in a given year relative to the total number of batteries sold in that same year was maximum in which year?
A2017
B2018
C2019
D2020 ✓ Correct
Correct answer: (D) 2020
Explanation
The answer is 2020.
In 2020, 105 thousand 4AH batteries were sold out of a total of 495 thousand.
That share is 105 divided by 495, times 100, which is about 21.21 percent.
In the other years the 4AH share is lower, for example about 20.58 percent in 2018 and 19.35 percent in 2019.
So the maximum 4AH share is in 2020.
The other options give a smaller share.
So the answer is 2020.
