Question
If in the word 'COMPUTER', all the consonants are changed
to 3rd preceding and all the vowels are changed to immediately preceding letter as per the English alphabetical series from left to right, and all the letters are then arranged as per the English alphabetical series from right to left, then the position of how many letters remains unchanged?Solution
Original word: COMPUTER Transformation: C -> Z (C - 3), O -> N (O - 1), M -> J (M - 3), P -> M (P - 3), U -> T (U - 1), T -> Q (T - 3), E -> D (E - 1), R -> O (R - 3) Rearranged right to left: Z, T, Q, O, N, M, J, D None of the positions remain unchanged.
Quantity I: A vessel contains a mixture of milk and water in the ratio of 7 : 5. If 9 litre of mixture is sold and replaced by same amount of water then...
I. 2x² + 15 x - 27 = 0
II. 3 y² + 25 y - 18 = 0
I. 4p² + 17p + 15 = 0
II. 3q² + 19q + 28 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 32x + 207 = 0
Equation 2: y² - 51y + 648 = 0
I. x2 + (9x/2) + (7/2) = - (3/2)
II. y2 + 16y + 63 = 0
I.70x² - 143x + 72 = 0
II. 80 y² - 142y + 63 = 0
I. x2 – 13x + 40 = 0
II. 2y2 – 15y + 13 = 0Â
I. 7x² + 27x + 18 = 0
II. 19y² - 27y + 8 = 0
In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between 'p' and 'q' and choose...
l. x2 - 16x + 64 = 0
II. y2Â = 64
