Answers :
Directions (1-5) :
1) Answer: E
59 + 2³ = 67
67 + 3³ = 94
94 + 4³ = 158
158 + 5³ = 283
2) Answer: D
39 – 13 = 26
26 + 21 = 47
47 – 29 = 18
18 + 37 = 55
55 – 45 = 10
3) Answer: B
96 * 5 = 480
480 / 4 = 120
120 * 5 = 600
600 / 4 = 150
150 * 5 = 750
4) Answer: A
85 + 7 * 3 = 106
106 – 8 * 4 = 74
74 + 9 * 5 = 119
119 – 10 * 6 = 59
59 + 11 * 7 = 136
(Or)
The alternative difference,
85 – 11 = 74, 74 – 15 = 59
106 + 13 = 119, 119 + 17 = 136
5) Answer: D
25 + 10 * 1² = 35
35 + 10 * 2² = 75
75 + 10 * 3² = 165
165 + 10 * 4² = 325
325 + 10 * 5² = 575
(Or)
The difference of difference is, 30, 50, 70, 90,…
Directions (6 – 10):
Total = 16000
35% of the total products are product B
Total products of B type = 35% 16000 = 5600
Ratio of plastic and metallic products in product B is 4:3
Plastic products of product B = 4/7 * 5600 = 3200
Metallic products of product B = 3/7 * 5600 = 2400
Plastic products of product A = 110% (number of plastic products of product B)
= > 110 % 3200 = 3520
Ratio of metallic products of product C and the number of plastic product of product A is 3:5 respectively
Metallic products of product C = 3/5 * 3520 = 2112
Number of Metallic products of product A = 80% of 2400 =1920
Total products of B = 5600
Total products of A = 3520 + 1920 = 5440
Total Products of C = 16000 – (5600 + 5440) = 4960
Total Plastic products of Product C = 4960 – 2112 = 2848
6) Answer: D
Difference between the plastic materials and the metallic materials of product C
= 2848 – 2112
=736
7) Answer: C
Required Ratio = 1920: 2400 = 4: 5
8) Answer: E
Total = 5440 + 5600 = 11040
9) Answer: A
Number of plastic materials of product A = 3520
Total product of B = 5600
Required percentage = (3520 / 5600) * 100 = 62.85 % ≈ 63%
10) Answer: E
Difference = 3200 – 1920 = 1280
