Answer: (d)

Here, each letter of the word CLOUD is written as three letters forward and one letter backward alternately. Following this CLOUD becomes FKRTG. After that, reverse the order of the result obtained in the previous operation. Thus, FKRTG becomes GTRKF. Similarly, SIGHT will change its form as follows: SIGHT → VHJGW → WGJHV

Answer: (b)

A real tough one! If we number the letters of the word from 1 to 6, first rearrange the letters in the order 615243. Next, to this reversed order of letters, apply the following alternately: move three letters ahead; go one letter backward. Thus NUMBER first becomes RNEUBM.

Then R + 3 = U, N – 1 = M,

E + 3 = H, U – 1 = T, B + 3 = E, M – 1 = L. So the final code is UMHTEL.

Similarly, SECOND → DSNEOC → GRQDRB
