Answer 2

Answer:

PEN is coded as RHS

Step-by-step explanation:

The position of the letters in the alphabet is assigned as A (= 1), B (= 2), C (= 3), D (= 4), E (= 5), F (= 6), G (= 7), H (= 8), I (= 9), J (= 10), K (= 11), L (= 12), M (= 13), N (= 14), O (= 15), P (= 16), Q (= 17), R (= 18), S (= 19), T (= 20), U (= 21), V (= 22), W (= 23), X (= 24), Y (= 25) and Z (= 26).

Now, B O O K

= 2 + 15 + 15 + 11

= 2 (+2) + 15 (+3) + 15 (+5) + 11 (+7)

= 4 + 18 + 20 + 18

= D R T R

So we see that the prime numbers are added consecutively starting from 2.

Then, P E N

= 16 + 5 + 14

= 16 (+2) + 5 (+3) + 14 (+5)

= 18 + 8 + 19

= R H S

Therefore PEN is coded as RHS.
