Question
If ‘JACKET’ is coded as ‘MDFHBQ’ and
‘UPDATE’ is coded as ‘XSGXQB’, then what is the code for ‘REMIND’?Solution
The logic followed here is as follows: The word is divided into two equal halves. The letters in the first half, from the left end, are replaced by third succeeding letter as per English alphabetical order. The letters in the second half are replaced by the third preceding letter as per English alphabetical order. JACKET → MDFHBQ UPDATE → XSGXQB REMIND → UHPFKA
I. 2x² + 15 x - 27 = 0
II. 3 y² + 25 y - 18 = 0
I. 5q = 7p + 21
II. 11q + 4p + 109 = 0
I. x ² + 5 x + 6 = 0                Â
II. y²+ 7 y + 12= 0
