Solution:

Concept:

First substitute the given code symbols, then evaluate using BODMAS.

Explanation:

Given:

+ \rightarrow \times

,

- \rightarrow +

,

\times \rightarrow \div

,

\div \rightarrow -

.

So the expression becomes:

11 + 50 - 150 \div 200 \quad \Rightarrow \quad 11 \times 50 + 150 - 200

Multiply first:

11 \times 50 = 550
