If B denotes + E denotes – and D denotes × then :
10B5E4D4 = ?

Correct option is C

Given:

1. The encoded operators are:
- B denotes + (addition),
- E denotes – (subtraction),
- D denotes × (multiplication).
2. Expression: 10B5E4D4.

Formula Used:

1. Replace the encoded operators with their respective mathematical symbols.
2. Follow the BODMAS rule (order of operations):
- Perform multiplication (×) first,
- Then addition (+),
- Finally subtraction (–).

Solution:

Step 1: Decode the Expression

10B5E4D4 = 10 + 5 - (4 × 4)

Step 2: Follow BODMAS Rule

1. Perform 4 × 4:
4 × 4 = 16
2. Replace and compute the remaining operations:
10 + 5 - 16
3. Perform addition:
10 + 5 = 15
4. Perform subtraction:
15 - 16 = -1

Final Answer:

The final result is -1.
