Solution:
Direction (Q. 1-5):
Total number of students studying Mechanical Engineering = 2400
Total number of students studying Computer Science = 2400 – 600 = 1800
Let the total number of students studying Engineering Application be x.
Then, x × 32% = 1800
x = (1800 × 100) / 32 = 5625
Now, total number of students studying engineering specialisation in college A = 2/ 3 of the total number of students studying in college A
Total number of students studying in College A  = 5625 × (3 / 2) = 8437.5 ≈ 8437
Again, total number of students studying Management specialisation = 8437 – 5625 = 2812
Let the number of students studying HR be y.
Then in Marketing  = y + 112
y + y + 112 = 2812 or, 2y = 2812 – 112 = 2700
y = (2700 / 2) = 1350
In marketing = 1350 + 112 = 1462
Now, the number of students studying Electrical Engineering = 5625 – 2400 – 1800 = 1425

1). Redq % = (No. of students studying marketing / No. of students studying mechanical) × 100
= (1462 / 2400) ×100 = (731 / 12)% = 60 11/12%

2). Average = (1800 + 1425 + 1462) / 3 = 4687 / 3 = 1562.33 ≈ 1562

3). Number of students studying in Collage A = 8437

4). Reqd ratio = (No. of students studying (Mech + Elec) / No. of students studying Marketing)
= (2400 + 1425) / 1462 = 3825 / 1462 = 225 / 86
= (34.61 / 13.23) = 34 / 13 = 34 : 13

5). Total number of female students in Engineer = (3 / 7) ×5625 ≈ 2410
Total number of male students in Engineering = 5625 – 2410 = 3215
Now, the number of female students studying Management = (2410 / 2) = 1205
Total number of students studying Management = 2812
Number of male students studying management = 2812 – 1205 = 1607 ≈ 1600

Directions (Q. 6-10)
Number of female players  = 1000 × (2/5) = 400
Number of male players= 1000 × (3/5) =600
Let the number of Rugby players be x.
Then, the number of Cricket players will be 2x.
According to the question,
x + 2x = 1000 – (200 + 150 + 80)
Or, x =190
 Sports Total players M F Hockey 1000 × (20/100) - 200 200 × (3/5) - 120 200 × (2/5) -80 TT 150 150 ×(2/3) = 100 150 × (1/3) = 50 Polo 1000 ×(8/100) = 80 80 × (50/100) = 40 40 Cricket 2x = 380 380 ×(70/100) =266 114 Rugby X = 190 74 116

6). Reqd difference = 266 – 116 = 150

7). Reqd % = (120/40) ×100 = 300%

8). Total number of female players in Polo, Rugby and TT = (40 + 50 + 116) = 206
