Answers :
Direction (1-5) :
1). Answer: c)
Explanation:
The ratio between the total number of male to that of female students in BBA = 3 : 2
The central angle corresponding to the female students in BBA
= > 360*(15/100)*(2/5)
= > 21.60
2). Answer: a)
Explanation:
The total number of male students in MBA
= > 60 % of total number of students in MBA
= > (60/100)*3500*(8/100) = 168
The ratio between the total number of male students in MBA to that of total number of female students in B. Sc = 4 : 5 (4x, 5x)
4x = 168
X = 42
The total number of female students in B. Sc = 5x = 210
The total number of students in B. Sc = 3500*(28/100) = 980
The total number of male students in B. Sc = 980 – 210 = 770
3). Answer: d)
Explanation:
The total number of students didn’t participate any sports of department of M. Com and BA together
= > 3500*(12/100)*(75/100) + 3500*(20/100)*(60/100)
= > 315 + 420 = 735
4). Answer: b)
Explanation:
The total number of BBA students
= > 3500*(15/100) = 525
The total number of BA students
= > 3500*(20/100) = 700
Required difference = 700 – 525 = 175
5). Answer: c)
Explanation:
The total number of male to that of female students in B. Com = 3 : 2
The total number of female students in B.Com
= > 3500*(17/100)*(2/5) = 238
Total number of students in MBA = 3500*(8/100) = 280
Required % = (238/280)*100 = 85 %
Direction (6-10) :
6). Answer: a)
Explanation:
The average marks scored by all the given students in Maths = 87
The total marks scored by all the given students in Maths = 87*6 = 522
The ratio between the marks scored by Mathan to that of Prithvi in Maths = 9 : 8 (9x, 8x)
The total marks scored by Mathan and Prithvi in Maths
= > 522 – (85 + 92 + 81 + 94)
= > 522 – 352 = 170
According to the question,
9x + 8x = 170
17x = 170
X = 10
The marks scored by Prithvi in Maths = 8x = 80 marks
7). Answer: d)
Explanation:
The total marks scored by Science of all the given students together
= > 84 + 77 + 80 + 75 + 85 + 80 = 481
The average marks scored by all the given students in Sanskrit = 76
The total marks scored by Sanskrit of all the given students together
= > 76*6 = 456
Required difference = 481 – 456 = 25
8). Answer: b)
Explanation:
The total marks scored by Ganesh in all the given subjects together
= > 66 + 85 + 72 + 77 + 80 = 380
The percentage of marks scored by Ganesh in all the given subjects together
= > (380/500)*100 = 76 %
9). Answer: a)
Explanation:
The ratio between the marks scored by Mathan and Pratheep in Social = 6 : 5
6x = 78
X = 13
The marks scored by Pratheep in Social = 65
Total marks scored by Pratheep in Social, Science and Sanskrit = 219
The marks scored by Pratheep in Sanskrit = 219 – (65 + 80) = 74
The average marks scored by Prithvi in Maths and Social = 83
The marks scored by Prithvi in Maths = (83*2) – 86 = 80
Required ratio = 74 : 80 = 37 : 40
10). Answer: c)
Explanation:
Total marks scored by Ragu in Science and Sanskrit together
= > 80 + 86 = 166
Total marks scored by Mathan in English and Social together
= > 82 + 78 = 160
Required % = (166/160)*100 = 103.75 %
