Answers :
Directions (1-5) :
1) Answer: D
11 + (22Â + 2) = 17
17 + (32Â + 3) = 29
29 + (42Â + 4) = 49
49 + (52Â + 5) = 79
79 + (62Â + 6) =Â 121
The wrong number is 119
2) Answer: A
21 * 2 – 3 = 39
39 * 3 – 4 = 113
113 * 4 – 5 = 447
447 * 5 – 6 = 2229
2229 * 6 – 7= 13367
The wrong number is 450
3) Answer: D
(10 – 2) * 2 = 16
(16 – 2) * 3 = 42
(42 – 2) * 4 = 160
(160 – 2) * 5 = 790
(790 – 2) * 6 = 4728
The wrong number is 4730
4) Answer: D
90 * 1 – 10 = 80
80 * 2 – 15 = 145
145 * 3 – 20 = 415
415 * 4 – 25 = 1635
1635 * 5 – 30 = 8145
The wrong number is 8140
5) Answer: E
1 + 93Â = 730
730 + 73Â = 1073
1073 + 53Â = 1198
1198 + 33Â = 1225
1225 + 13Â =Â 1226
The wrong number is 1240
Direction (06 – 10):
Total number of rotten fruits = x
Number of rotten Guava = 45
Number of rotten apple = x * 30/100 = 3x/10
Number of rotten Banana = 22/100 * x = 11x/50
Number of rotten Orange = 18/100 * x = 9x/50
Number of rotten Mango = x * 12/100 = 6x/50
3x/10 + 11x/50 + 9x/50 + 6x/50 + 45 = x
15x + 11x + 9x + 6x + 2250 = 50x
9x = 2250
x = 250
Number of rotten apple = 250 * 30/100 = 75
Number of rotten Banana = 22/100 * 250 = 55
Number of rotten Orange = 18/100 * 250 = 45
Number of rotten Mango = 250 * 12/100 = 30
Total number of good fruits = 650 – 250 = 400
Number of good apple = 400 * 18/100 = 72
Number of good Banana = 1/5 * 400 = 80
Number of good Mango = 30/100 * 400 = 120
Number of good Orange = 22/100 * 400 = 88
Number of good Guava = 400 – 72 – 80 – 120 – 88 = 40
6) Answer: D
Required percentage = 30/40 * 100 = 75%
7) Answer: D
One dozen Mango = 80 * 120/100 = Rs.96
Total dozen of mango = 120/12 = 10 dozen
Total revenue = 10 * 96 = Rs.960
8) Answer: A
Required ratio = (55 + 80):(45 + 40)
= 135:85
= 27:17
9) Answer: C
Difference = 400 – 250 = 150
10) Answer: A
Total cost of Good Apple = 72 * 10 = 720
Total cost of Good Orange = 88 * 8 = 704
Total cost of Good Guava = 40 * 5 = 200
Total revenue = 720 + 704 + 200 = 1624
