Answers :
1) Answer: E
Required average = (620 + 860 + 1040 + 1100 + 960 + 700)/6
= 5280/6
= 880
2) Answer: D
Required difference = (900 + 1080 + 540 + 760 + 840 + 1000) – 760
= 5120-760
= 4360
3) Answer: B
Apple = 720 + 620 + 900 = 2240
Grapes = 840 + 860 + 1080 = 2780
Orange = 640 + 1040 + 540 = 2220
Lemon = 580 + 1100 + 760 = 2440
Pomegranate = 1020 + 960 + 840 = 2820
Guava = 960 + 700 + 1000 = 2660
4) Answer: C
Required percentage = 1020/(720 + 840 + 640 + 580 + 1020 + 960) * 100
= (1020/4760) * 100
= 21.42%
5) Answer: A
Required percentage= 1080/(960 + 700 + 1000) * 100
= (1080/2660) * 100
= 40.6%
6) Answer: C
Number of buildings constructed in Madurai = 60/40 * 1600 = 2400
Number of buildings constructed in Kovai = 70/30 * 1800 = 4200
Required percentage = 2400/4200 * 100 = 57.14%
7) Answer: E
Total number of buildings in Trichy = 100/60 * 2400 = 4000
Total number of buildings in Chennai = 100/70 * 2800 = 4000
Difference = 4000 – 4000 = 0
8) Answer: E
Number of buildings constructed in Salem = 80/20 * 1200 = 4800
Number of buildings constructed in Kovai = 70/30 * 1800 = 4200
Number of buildings constructed in Chennai = 30/70 * 2800 = 1200
Required average = (4800 + 4200 + 1200)/3
= 3400
9) Answer: A
Total number of buildings in Trichy = 100/60 * 2400 = 4000
Number of buildings are non government = 4000 * (100 – 45)/100 = 2200
10) Answer: B
Number of buildings constructed in Madurai = 60/40 * 1600 = 2400
Total number of buildings in Salem = 4800 + 1200 = 6000

Answers :
11) Answer: B
Difference in P = 250 – 200 = 50
Q = 250 – 100 = 150 (Highest difference)
R = 200 – 150 = 50
S = 280 – 150 = 130
T = 250 – 220 = 30
12) Answer: A
Girls in school R = 200
Girls in P and Q = 250 + 100 = 350
Required % = 200/350 * 100 = 57.14%
13) Answer: C
Boys in the schools P, R and T = 200 + 150 + 250 = 600
Girls in the schools P, R and T = 250 + 200 + 220 = 670
Required ratio = 600: 670 = 60: 67
14) Answer: B
Number of students in P = 200 + 250 = 450
Number of students in S = 150 + 280 = 430
Required % = 450/430 * 100 = 104.7%
15) Answer: E
Number of students in P = 200 + 250 = 450
Number of students in Q = 100 + 250 = 350
Number of students in R = 150 + 200 = 350
Number of students in S = 150 + 280 = 430
Number of students in T = 220 + 250 = 470 (Highest)
16) Answer: C
Required difference = (420 + 280)/2 – (360 + 240)/2
= 700/2 – 600/2
= 350 – 300
= 50
17) Answer: B
Number of gift vouchers = 125/100 * 280
= 350
Difference = 350 – 320 = 30
