Answers
86. Given : 5 , 15 , 50 , 120 , 235 , 405 , ?
✿ The Difference between 5 and 15 is 10
✿ The Difference between 15 and 50 is 35
✿ The Difference between 50 and 120 is 70
✿ The Difference between 120 and 235 is 115
✿ The Difference between 235 and 405 is 170
The Inbuilt Series is 10 , 35 , 70 , 115 , 170 , X
✿ The Difference between 10 and 35 is 25
✿ The Difference between 35 and 70 is 35
✿ The Difference between 70 and 115 is 45
✿ The Difference between 115 and 170 is 55
⇒ The Difference between 170 and X should be 65
⇒ X - 170 = 65
⇒ X = 235
⇒ The Difference between 405 and ? should be 235
⇒ ? - 405 = 235
⇒ ? = 405 + 235
⇒ ? = 640
✿ Option (4) is the Answer
87. We know that : T is 20th Letter in the Alphabets
⇒ T = (20 + 1)² = 21² = 441
We know that : M is 13th Letter in the Alphabets
⇒ M = (13 + 1)² = 14² = 196
We know that : O is 15th Letter in the Alphabets
⇒ O = (15 + 1)² = 16² = 256
⇒ W is 23rd Letter in the Alphabets
⇒ W = (23 + 1)² = 24² = 576
✿ Option (3) is the Answer
88. We know that : 12³ = 1728
⇒ 12³ - 1 = 1727
We know that : 6³ = 216
⇒ 6³ - 1 = 215
We know that : 8³ = 512
⇒ 8³ - 1 = 511
We know that : 10³ = 1000
⇒ 10³ - 1 = 999
But the 2nd Option is 1001
✿ So, Option (2) is the Odd One Out
