In which of the following pairs of schools is the percentage of students who passed without distinction to those who appeared the same?

After reading the chart, we can get the data:

School   Total    Passed  Distinction  Without distinction     
A            800      640          300              340
B           1050     840          350              490
C           1200     920          450              470
D            750      600          260              340
E            900      750          330              420
F           1500     1000         450              550

Finding the percentage of students who passed without distinction to the total number of students who appeared we get:
A = $$\frac{340}{800}\times\ 100=42.5\%$$
B = $$\frac{490}{1050}\times\ 100=46.67\%$$
C = $$\frac{470}{1200}\times\ 100=39.1667\%$$
D = $$\frac{340}{750}\times\ 100=45.33\%$$
E = $$\frac{420}{900}\times\ 100=46.667\%$$
F = $$\frac{550}{1500}\times\ 100=36.67\%$$

We can see that B and E have the same percentage which aligns with option B. 
Therefore, Option B will be the correct answer.
