If the first and last i.e., the first and the 26th letter of the English alphabet are paired, the second and the 25th, the third and the 24th and so on are paired, which of the following would be such a pair?
- (a)
CW
- (b)
GR
- (c)
EV
- (d)
IP
If first and last alphabets are paired, we are talking of making pairs of x and 27 - x.
If you find the mathematical way difficult, make sure you use the alphabet scheme. But be quick in your decision. Look for the simplest method always.
Hence EV is such a pair.
