Question
Select the letter cluster which does not belong to the
same group from the given alternatives.Solution
The logic followed here is: From left, the 2nd letter is 3rd succeeding letter of 1st letter, the 3rd letter is 4 th succeeding letter of 2nd letter as per the English alphabetical series. CFJ: C + 3 = F, F + 4 = J GJN : G + 3 = J, J + 4 = N VXA : V + 3 = Y, Y + 4 = C ORV : O + 3 = R, R + 4 = V TWA : T + 3 = W, W + 4 = A
- Suppose [a + (1/16a)] = 3, then the value of [16a³ + (1/256a³)] is:

If (a + b) = 9 and (a2 + b2) = 53, then find the value of (a × b).
If (10 a³ + 4b³): (11a³ — 15b³) = 7:5, then (3a + 5b): (9a - 2b) = ?
- If p = 25 - q - r and pq + r(p + q) = 256, then find the value of (p² + q² + r²).
- If x + 4y = 26 and 4x + y = 41, then find the value of (x - y).
If (a + b) = 7 and ab = 10, then find the value of (a 2 Â + b 2 ).
If 8x3Â - 125y3Â = (2x - Ay) X (Bx2Â + 25y2Â + Cxy), then find the value of 3 X (2A + 6B) - 2C.
