Letter to Number Coding

In Letter to Number Coding questions, either numerical code values are assigned to a word or alphabetical code letters are assigned to the numbers. we have to required to analyse the code as per the directions in the questions.

Example : If PKROK is coded as 72962 and KRRPK as 29972, then how can NJMLZ be coded? 

Solution : 51430

According to the given code system, P is coded as 7, K as 2, R as 9 and O as 6. That means code of NKMLZ does not have either 7, 2, 9 or 6. Hence, required code will be 51430

Example : If B = 2 and BAG = 10, then BOX =? 

Solution : 41

As, B = 2,
and BAG = 2 + 1 + 7 = 10
Similarly, BOX = 2 + 15 + 24 = 41.

Example : If D is coded as 4 and C O V E R is coded as 63, then BASIS will be coded as?

Solution : 50 

Clearly, in the given code, A = 1. B = 2, C = 3 …. so that C O V E R is coed as 3 + 15 + 22 + 5 + 18 = 63. [C + O + V + E + R]

Now, in B A S I S, B = 2, A = 1, S = 19, and I = 9. Thus, B A S I S will be coeded as 2 + 1 + 19 + 9 + 19 = 50.
