Directions for Q33-35. One of the numbers is wrong in the following series. Identify the wrong number in the following series: Q33) 5, 8, 3, 11, -5, 27 1) 8 2) 11 3) -5 4) 27 Solution: Difference between the numbers is 2,-4,8,-16,32. Wrong number is 8. Hence, option 1. Q34) 2, 6, 12, 21, 30, 42 1) 2 2) 12 3) 21 4) 42 Solution: Logic is 22 - 2 = 2, 32 - 3 = 6, 42 - 4 = 12, 52 - 5 = 20, 62 - 6 = 30, 72 - 7 = 42 Wrong number is 21. Hence, option 3. Q35) 5, 26, 122, 340, 1328, 2194 1) 122 2) 26 3) 340 4) 1328 Solution: Logic is 23 - 3 = 5, 33 - 3 = 24, 53 - 3 = 122, 73 - 3 = 340, 113 - 3 = 1328, 133 - 3 = 2194 Wrong number is 26. Hence, option 2. Directions for Q36-37. In the following series one wrong number is given, find out the wrong number and identify the number that should replace the wrong number. Q36) 68, 36, 20, 12, 7.5, 6, 5 1) 7.5 2) 8 3) 15 4) 7 Solution: Logic is 68 - 32 = 36, 36 - 16 = 20, 20 - 8 = 12, 12 - 4 = 8, 8 - 2 = 6, 6 - 1 = 5 Wrong number is 7.5 and it should be replaced with 8. Hence, option 2. Q37) 2, 1, 13, 19, 99, 211 1) 11 2) 99 3) 97 4) 13 Solution: Logic is 2×3 - 5 = 1, 1×3 + 10 = 13, 13×3 - 20 = 19, 19×3 + 40 = 97, 97×3 - 80 = 211 Wrong number is 99 and it should be replaced with 97. Hence, option 3. |
