A man travels $2,\text{km}$ to the north and turns east and travels $10,\text{km}$, and again he turns north and travels $3,\text{km}$ and again turns to the east and travels $2,\text{km}$. How far is he from the starting point?

Solution
Total east $=10+2=12$, total north $=2+3=5$.
Distance $=\sqrt{12^{2}+5^{2}}=\sqrt{144+25}=\sqrt{169}=13,\text{km}$.

Solution
$A+B$ (10 years ago) $=40$. Today $A+B=40+20=60$.
Today $A+B+C=3\times30=90 \Rightarrow C=90-60=30$.
After $5$ years $=30+5=35$.

1
2
3
4
Solution
Each letter is shifted forward by one place in the alphabet:
$A \to B,\ P \to Q,\ L \to M,\ E \to F,\ S \to T.$
Applying the same to “ORANGE”:
$O \to P,\ R \to S,\ A \to B,\ N \to O,\ G \to H,\ E \to F.$
So “ORANGE” $\to$ PSBODF.

Solution
Shift each letter one step forward in the alphabet:
$B\to C,\ E\to F,\ A\to B,\ N\to O$ gives “CFBO”.
Apply to “CORN”: $C\to D,\ O\to P,\ R\to S,\ N\to O$ $\Rightarrow$ letters $D,P,S,O$.
Thus code is DPOS.
