Question
Four of the following five pair of letter cluster are
alike in a certain manner and one is different. Select the one which is different.ÂSolution
The logic followed here is as follows: In each letter cluster from the left end, The 2nd letter is the 2nd succeeding letter of the 1st letter and the 3rd letter is the 4th succeeding letter of the 2nd letter as per the English alphabetical series. In option 'A', N + 2 = P, P + 4 = T In option 'B', Q + 2 = S, S + 4 = W In option 'C', U + 2 = W, W + 4 = A In option 'D', S + 2 = U, U + 4 = Y In option 'E', O + 2 = P, P + 4 = T ≠V

If x²- 5x + 1 = 0, what is the value of x² + 1/x2?
Evaluate:
(24/6) + 3 × (5 - 2)2
(64/25)? × (125/512)?-1 = 5/8
(82 + 62 ) × 1.25 + 20% of 145 = ? – 40% of 65Â
[(15)³ × (8)²] ÷ (90 × 6) = ?²
(500 × 6 ÷ 10) - (√256 + 8) = ?
(0.1 × 0.2 × 0.3) + (0.3 × 0.4 × 0.5) =?
