If the total items sold by A and B over all five days are 4000 and 4400 respectively, then the items sold by B on Tuesday are ______ % more than the items sold by A on Friday.
A37.5 ✓ Correct
B23.5
C32.25
D42.5
Correct answer: (A) 37.5
Explanation
It is 37.5 percent more, so that is the answer.
A's known days sum to 3200, so A on Friday is 800.
B's known days sum to 3300, so B on Tuesday is 1100.
The excess is 1100 minus 800, which is 300.
300 over 800 is 0.375.
That is 37.5 percent.
