1. D) Following the common explanation, we get
Amount collected from all the parkings on Sunday = 110 × (1.2 × 14) + 90 × (1.2 × 32) + 70 × (1.2 × 14) + 50 × (1.2 × 12) + 100 × (1.2 × 24) + 80 × (1.2 × 20)
= (110 × 16.8) + (90 × 38.4) + (70 × 16.8) + (50 × 14.4) + (100 × 28.8) + (80 × 24)
= 1848 + 3456 + 1176 + 720 + 2880 + 1920 = 12000

2. C) Total amount collected from Crossroad's parking on Monday = 6300 – [70 × (6 + 12 + 25 + 22 + 14)] = 6300 – (70 × 79) = 6300 – 5530 = 770 
And the total amount collected from TDI's parking on Friday = 7600 – [ 80 × (14 + 16 + 25 + 12 + 20)] = 7600 – (80 × 87) = 7600 – 6960 = 640
Hence, the total amount collected from parking of Corssroad and TDI together = 770 + 640 = 1410

3. C) Amount collected from Spencer and GIP on Thursday = (22 × 50) + (18 × 100)= 1100 + 1800 = 2900
And The total amount from Square mall's parking from Tuesday to Thursday = 9450 – 90(25 + 32 + 10) = 9450 – (90 × 67)
= 9450 – 6030 = 3420
Required difference = 3420 2900 = Rs. 520

4. A) Amount collected from parking of City Walk on Saturday = 8580 – 110(8 + 17 + 12 + 18 + 9) = 8580 – 110 × 64 = Rs. 1540
   Charge per vehicle of City Walk on Saturday = 1540/110 = Rs.14 per vehicle
Similarly, Amount collected from parking of TDI on Friday = 7600 – 80(14 + 16 + 25 + 12 + 20) = 7600 – (80 × 87) = 7600 – 6960 = Rs. 640
   Charge per vehicle of TDI on Friday = 640/80 = Rs.8 per vehicle
   Required % = 14/8 × 100 = 175%

5. B) Total number of amount charge on vehicle in City walk parking on Saturday = 8580 – 110 (8 + 17 + 12 + 18 + 9)
= 8580 – (110 x 64) = 8580 – 7040 = 1540
Therefore, the amount per vehicle charge on Saturday = 1540 / 110 = 14
Similarly, Square on Saturday = 32 × 90 = 2880
In Crossroad = 14 × 70 = 980
In Spencer = 12 × 50 = 600
In GIP = 24 × 100 = 2400
In TDI = 20 × 80 = 1600
Total amount collected from all parkings on saturday = 1540 + 2880 + 980 + 600 + 2400 + 1600 = 10000
Reqd average = 10000/500 = Rs.20

(6 – 10):
No. of girl students in the Faculty of Arts = 840
Percentage of girl students in the Faculty of Arts = 100 – (27 + 22 + 16) = 100 – 65 = 35%
35% = 840 => 100% = 2400
   Boy students = 5200 2400 = 2800

6. B) No. of boy students in the Faculty of Arts after the transfer of 92 boys from the faculty of Engineering = 308 + 92 = 400
And the number of girl students in the faculty of Arts = 840 – 70 = 770
   Reqd ratio = 400 : 770 = 40 : 77

7. E) Req. avg = (560 + 840 + 528 + 308 + 840)/3 = 3076/3 = 1025

8. E) Total no. of boy students in the Faculty of Commerce and the Faculty of Science = 840 + 700 = 1540
Total no. of students in these two faculties = 840 + 528 + 700 + 384 = 2452
   Reqd % = 62.8%

9. B) Total increase in students = 20% of 700 + 25% of 308 + 60 = 140 + 77 + 60 = 277
   Reqd % = 277/2800 × 100 = 9.89%

10. A) Let the number of boy students who drop out the college be x
Then, (700 – x)/(384 – x) = 149/70
=> 70 (700 – x) = 149 (384 – x) => 149x – 70x = 149 × 384 – 700 × 70
=> 79x = 57216 – 49000 = 8216 => x = 8216/79 = 104
   Total number of students who drop out the college = 104 × 2 = 208

11. C) C = 1200 * (35% + 10%) = 1200 * 45% = 540

12. B) Required Ratio = 100 : 144 = 13 : 18

13. C) Total number of student in mining and Computer Science Engineering together
