In a code, SKY is written as 165 and RAIN is written as 168. How is CLOUD written in that code?

Explanation

1. 01

   SKY: $19 + 11 + 25 = 55$, and $165 = 55 \times 3$. RAIN: $18 + 1 + 9 + 14 = 42$, and $168 = 42 \times 4$.

2. 02

   So the code is the sum of the positions multiplied by the number of letters.

3. 03

   CLOUD: $3 + 12 + 15 + 21 + 4 = 55$, and $55 \times 5 = 275$.
