Explanation

Check with TODAY:

T = 20, O = 15, D = 4, A = 1, Y = 25  

Sum = 20 + 15 + 4 + 1 + 25 = 65  

Number of letters = 5  

65 + 3 = 68  

So pattern: Sum + 3 = Code

Now for BOOK:  

B = 2, O = 15, O = 15, K = 11  

Sum = 2 + 15 + 15 + 11 = 43  

Number of letters = 4  

43 + 0 = 43

Given: SCHOOL = TDIPPM

Check letter by letter:

S -> T = +1  

C -> D = +1  

H -> I = +1  

O -> P = +1  

O -> P = +1  

L -> M = +1  

Pattern: Each letter is increased by 1

Now code for BOOK:

B -> C  

O -> P  

O -> P  

K -> L  

Code = CPNL

Explanation

The code is formed by replacing each letter with the letter 2 positions ahead in the English alphabet:

W → Y

H → J

I → K

T → V

E → G

Similarly:

B → D

L → N

A → C

C → E

K → M

So, BLACK → DNCEM.

Explanation

Start at point O.

1. Walk 10 m north  

2. Walk 15 m east  

3. Walk 10 m south  

Net movement north-south: 10 m north - 10 m south = 0 m  

Net movement east-west: 15 m east  

So final position is 15 m east of the starting point.  

He is in the East direction from the starting point.
