In Number coding type of questions, either numerical code values are assigned to a word or alphabetical code letters are assigned to the numbers. The candidate is required to analyse the code as per the directions.
If AT = 20, BAT = 40, then CAT will be equal to
Talking A = 1,
B = 2,...., T = 20,....., Z = 26,
We have :
AT = A x T = 1 x 20 = 20.
BAT = B x A x T = 2 x 1 x 20 = 40.
Similarly, CAT = C x A x T = 3 x 1 x 20 = 60.
