Answers :
Directions (1-5) :
1) Answer: a)
163 – 16 = 4080
153 – 15 = 3360
143 – 14 = 2730
133 – 13 = 2184
123 – 12 = 1716
113 – 11 = 1320
2) Answer: c)
3 + (3 * 6) = 21
21 + (2 * 6) = 33
33 + (1 * 6) = 39
39 + (0 * 6) = 39
39 + (-1 * 6) = 33
3) Answer: a)
19 * 1 – 2 = 17
17 * 2 – 4 = 30
30 * 3 – 8 = 82
82 * 4 – 16 = 312
312 * 5 – 32 = 1528
4) Answer: e)
94 + 1 = 95
95 + 1 + 2 = 98
98 + 1 + 2 + 3 = 104
104 + 1 + 2 + 3 + 4 = 114
114 + 1 + 2 + 3 + 4 + 5 = 129
5) Answer: c)
2430 ÷ 1.5 = 1620
1620 ÷ 1.5 = 1080
1080 ÷ 1.5 = 720
720 ÷ 1.5 = 480
480 ÷ 1.5 = 320
Directions (6-10) :
6) Answer: b)
Difference of Airtel user in Chennai and Mumbai = 7000 – 5000 = 2000
Difference of Vodafone user in Delhi and Bangalore = 7000 – 3000 = 4000
Average = (2000 + 4000)/2 = 3000
7) Answer: c)
Required percentage = 8000/(7000 + 4000 + 6000) * 100 = 47%
8) Answer: d)
Average = (8000 + 7000 + 3000 + 4000)/4 = 5500
9) Answer: c)
Average Airtel and Jio users in Chennai = (5000 + 10000)/2 = 7500
Average of Vodafone and Jio users in Delhi = (3000 + 9000)/2 = 6000
Required ratio = 7500: 6000 = 5: 4
10) Answer: b)
Male user in Jio = 8000 * 60/100 = 4800
Female users in Jio = 8000 * 40/100 = 3200
Female users in Airtel = 80/100 * 6000 = 4800
Number of male users in Airtel = 20/100 * 6000 = 1200
Difference = (4800 + 3200) – (4800 + 1200) = 2000
