The given graph shows the performance of the students of schools A, B, C, D, E and F in a Board Examination. Study the graph and answer the questions that follow.
In which of the following schools is the number students who passed with distinction as a percentage of those students who failed the least?
For this part, we will also have to calculate the number of students who failed in each school.Â
adding that to our previous data table we get:
School   Total   Passed   Distinction   Without distinction  Failed
AÂ Â Â Â Â Â Â Â 800Â Â Â Â Â Â 640Â Â Â Â Â Â 300Â Â Â Â Â Â Â Â Â Â Â 340Â Â Â Â Â Â Â Â Â Â 160
BÂ Â Â Â Â Â Â 1050Â Â Â Â Â 840Â Â Â Â Â Â Â 350Â Â Â Â Â Â Â Â Â Â Â 490Â Â Â Â Â Â Â Â Â Â 210
CÂ Â Â Â Â Â Â 1200Â Â Â Â Â 920Â Â Â Â Â Â Â 450Â Â Â Â Â Â Â Â Â Â Â 470Â Â Â Â Â Â Â Â Â Â 280
DÂ Â Â Â Â Â Â Â 750Â Â Â Â Â Â 600Â Â Â Â Â Â 260Â Â Â Â Â Â Â Â Â Â Â Â 340Â Â Â Â Â Â Â Â Â Â 150
EÂ Â Â Â Â Â Â Â 900Â Â Â Â Â Â 750Â Â Â Â Â Â Â 330Â Â Â Â Â Â Â Â Â Â Â 420Â Â Â Â Â Â Â Â Â Â 150
FÂ Â Â Â Â Â Â 1500Â Â Â Â Â 1000Â Â Â Â Â Â 450Â Â Â Â Â Â Â Â Â Â Â Â 550Â Â Â Â Â Â Â Â Â Â 500
Calculating the students who passed with distinction as a percentage of students who failed for the given options we see,Â
Option A:Â $$\frac{470}{280}\times\ 100\approx\ 170\%$$
Option B:Â $$\frac{420}{150}\times\ 100\approx\ 280\%$$
Option C:Â $$\frac{490}{210}\times\ 100\approx\ 230\%$$
Option D:Â $$\frac{550}{500}\times\ 100\approx\ 110\%$$
We can see that Option D or School F has the least percentage in this category.Â
Therefore, Option D is the correct answer.Â
