Question

If ACNE is coded as 3,7,29,11, then BOIL will be coded as -

A

5, 31, 21, 25.

B

5, 29, 19, 25.

C

5, 31, 19, 25.

D

5, 29 19, 27.

Soln.
Ans: c

If n is the position of a letter in the alphabet, then the code is 2n + 1. A has position 1, so its code is 2x1 + 1 = 3, and so on.

B = 2, becomes 2x2 +1 = 5, O = 15 becomes 2x15 + 1 = 31, I is 9 becomes 19, and L is 12 becomes 25.
