The number of students qualifying from Schools A to G together in 2021 as a percentage of that in 2020 is
A140%
B120% ✓ Correct
C135%
D112%
Correct answer: (B) 120%
Explanation
The answer is 120 percent.
The total qualifying in 2020 is 750 and in 2021 it is 900.
So the 2021 total as a percent of the 2020 total is 900 divided by 750, times 100.
That equals 120 percent.
So the 2021 total is 120 percent of the 2020 total.
The other options do not match this value.
So the answer is 120 percent.
