Option 1 : D
Calculation:
Total number of students appeared = 1200
Numbers of students appeared in the examination from institutes A = 72°
⇒ (72/360 × 1200)
⇒ 240
Numbers of students appeared in the examination from institutes B = 54°
⇒ (54/360 × 1200)
⇒ 180
Numbers of students appeared in the examination from institutes C = 90°
⇒ (90/360 × 1200)
⇒ 300
Numbers of students appeared in the examination from institutes D = 105°
⇒ (105/360 × 1200)
⇒ 350
Numbers of students appeared in the examination from institutes E = 39°
⇒ (39/360 × 1200)
⇒ 130
Now,
Total number of students passed = 900
Numbers of students passed in the examination from institutes A = 15%
⇒ (900 × 15/100)
⇒ 135
Numbers of students passed in the examination from institutes B = 18%
⇒ (900 × 18/100)
⇒ 162
Numbers of students passed in the examination from institutes C = 30%
⇒ (900 × 30/100)
⇒ 270
Numbers of students passed in the examination from institutes D = 28%
⇒ (900 × 28/100)
⇒ 252
Numbers of students passed in the examination from institutes E = 9%
⇒ (900 × 9/100)
⇒ 81
The percentage of students of institutes A passed to the students who appeared from that institute = (135/240 × 100)
⇒ 56.25%
The percentage of students of institutes B passed to the students who appeared from that institute = (162/180 × 100)
⇒ 90%
The percentage of students of institutes C passed to the students who appeared from that institute = (270/300 × 100)
⇒ 90%
The percentage of students of institutes D passed to the students who appeared from that institute = (252/350 × 100)
⇒ 72%
The percentage of students of institutes E passed to the students who appeared from that institute = (81/130 × 100)
⇒ 62.30%
Now,
We can see that the percentage of B and C is same which is also the highest = 90%
So, the second highest percentage of students who passed to the students who appeared is from institute D = 72%
∴ The required answer is Institute D
