What will come in the place of '?' in the following equation, if '-' and '├╖' are interchanged and '├Ч' and '+' are interchanged? 17+13├Ч3├╖12тИТ4=?
206
211
221
241
221
Apply BODMAS after swapping the signs: (17 + 13) * 3 / 12 - 4. Remember: Division and Multiplication have the same priority from left to right.
Apply BODMAS after swapping the signs: (17 + 13) * 3 / 12 - 4. Remember: Division and Multiplication have the same priority from left to right.
Symbol Substitution
Replace '-' with '├╖', '├╖' with '-', '├Ч' with '+', and '+' with '├Ч'. The equation becomes: 17 ├Ч 13 + 3 - 12 ├╖ 4 = ?
BODMAS Application
First, perform division: 12 ├╖ 4 = 3. Equation: 17 ├Ч 13 + 3 - 3.
Final Calculation
Next, perform multiplication: 17 ├Ч 13 = 221. Then add and subtract: 221 + 3 - 3 = 221.
A: 206 is incorrect as it results from wrong order of operations. B: 211 is incorrect based on the sign conversion logic. D: 241 is incorrect as the arithmetic steps do not lead to this value.
C is correct because applying the interchanged operators and following BODMAS rules (17 * 13 + 3 - 3) leads to 221.
Always rewrite the full equation clearly after replacing signs to avoid missing any operator. When multiple operations have same priority, always solve from left to right.
