Answers :
Directions (1-5) :
1) Answer: c)
The average number of students in college P, Q and S together
= > (15 + 24 + 12)*(5000/100)*(1/3)
= > 850
2) Answer: b)
The total number of students in college Q and R together
= > (24 + 20)*(5000/100)
The total number of students in college S and U together
= > (12 + 11)*(5000/100)
Required difference = (5000/100)*(44 – 23)
= > 50*21 = 1050
3) Answer: a)
The total number of students didn’t go to any symposium from both the colleges together
= > (12/100)*5000*(85/100) + (18/100)*5000*(80/100)
= > 510 + 720 = 1230
4) Answer: d)
The ratio of male and female students in College R = 3: 2
The ratio of male and female students in College T = 1: 2
Total number of male in college R and T together
= > (20/100)*5000*(3/5) + (18/100)*5000*(1/3)
= > 600 + 300 = 900
Total number of female in college R and T together
= > (20/100)*5000*(2/5) + (18/100)*5000*(2/3)
= > 400 + 600 = 1000
Required difference = 1000 – 900 = 100
5) Answer: b)
Required % = (24/20)*100 = 120 %
Directions (6-10) :
6) Answer: a)
(78/3) + 45 = x – (12376/7)
26 + 45 = x – 1768
X = 26 + 45 + 1768
X = 1839
7) Answer: d)
(5/11) * 5038 + (56/100)*1250 = (x)2 – 35
2290 + 700 + 35 = x2
3025 = x2
X = 55
8) Answer: b)
6x× 22 = (48090/7) + 21642
6x× 22 = 6870 + 21642
6x = 28512/22
6x = 1296
6x = 64
X = 4
9) Answer: a)
x *100/160 of (280 – 120) = 330 + 3025
x *100/160= 3355
X = (3355*160)/100
X = 5368
10) Answer: c)
(92)5 ÷ (729/9)2 × (9 × 92)3 = (9)x + 5
910 ÷ (81)2 × (93)3 = (9)x + 5
910 ÷ 94 × 99 = (9)x + 5
910 – 4 + 9 = 9x + 5
915 = 9x + 5
15 = x + 5
x = 10
