Question 41

In certain code language, BOOK is coded as 139 and PEN is coded as 302. How will COPY be coded as in that language?

Solution

Given, BOOK is coded as 139 and PEN is coded as 302 in the code language

K + B = 13 and K - B = 9

P + N = 30 and P - N = 2

The code for word is the combination of sum and difference of values of first and last letters of the word.

Similarly, for COPY

Y + C = 28 and Y - C = 22

$$\therefore\ $$COPY is coded as 2822 in the code language

Hence, the correct answer is Option C
