Question

Book= 139, pen= 302, copy=‽?

Answer 1

copy = 2822

Given:

book = 139

pen = 302

To find:

Code for copy

Solution:

According to the given data, code for book is 139.

When the letters in "book" are written in terms of their alphabet positions, we obtain 2 15 15 11.

It can be observed that 11 + 2 = 13 and 11 - 2 = 9 and the combination of both forms the code.

Similarly, when the letters in "pen" are written in terms of their alphabet positions, we obtain 16 5 14. Code for pen is 302.

16 + 14 = 30 and 16 - 14 = 2 and the combination of both forms the code for "pen".

Therefore, it can be concluded that the code for a word is obtained by joining the sum and difference of alphabet positions of first and last letter.

For the word copy, when the letters are arranged in term of their alphabet positions, we obtain 3 15 16 25.

25 + 3 = 28 and 25 - 3 = 22

By combining, we obtain 2822.

Hence, copy = 2822.
