Solutions:

2.% of marks obtained by Alex in Bio
= (90/125) ร 100 = 72%
= % of marks obtained by Alex in Hindi.

3.56% of 150 = 84. Hence, five students will get grade A.

4. Quicker Method:Here, no need to calculate the % marks obtained by each student in Maths and Hindi together. Just check which two students have secured the least marks in Maths and Hindi together.

5.Maximum percentage difference in the marks obtained means: subtract the studentโs marks who secured the minimum marks from the oneโs who secured the maximum marks.
So, required % = (135 โ 72) / 150 ร 100 = 42%

6.Required % = (1200 / 14900) ร 100 = 8%

7.Total no. of Officers
= 2000 + 15000 + 17000 + 3500 + 14900 + 11360 + 9000 = 72760
Total no. of Clerks = 17650 + 15300 + 11000 = 105450
Required difference = 105450 โ 72760 = 32690

8.Required more %= [(11000 โ 9000) / 9000] ร 100 โ 22%

9.300% more means four times the number of Clerks in Bangalore, which is in Hyderabad.

10.No. of candidates in different centers:
Bangalore=9850;
Mumbai = 44470;
Delhi = 43910;
