In a code, BAG is written as 14 and ACE is written as 15. How is HID written in that code?

Explanation

1. 01

   The sums do not fit: BAG adds to 10, not 14. Try the product: B × A × G = $2 \times 1 \times 7 = 14$.

2. 02

   Check ACE: $1 \times 3 \times 5 = 15$. The code is the product of the letter positions.

3. 03

   HID: $8 \times 9 \times 4 = 288$.
