If 'A' stands for '+', 'B' stands for '×', 'C' stands for '+' and 'D' stands for '-', then what will come in place of the question mark (?) in the following equation? 47 D 25 A 5 C 2 B 9 = ?
60
Given the equation: 47 D 25 A 5 C 2 B 9 = ?
And the following substitutions:
- A = +
- B = ×
- C = +
- D = -
We substitute these values into the equation:
47 - 25 + 5 + 2 × 9 = ?
Following the order of operations (PEMDAS/BODMAS), we perform multiplication before addition and subtraction:
47 - 25 + 5 + 18 = ?
Now, we perform addition and subtraction from left to right:
22 + 5 + 18 = ?
27 + 18 = ?
45 = ?
There appears to be a mistake in either the question or the provided answer options. Let's re-examine the calculations.
Let's try a different approach, assuming the order of operations is strictly left to right (which is not standard mathematical practice, but it's possible the question intends this):
47 - 25 = 22
22 + 5 = 27
27 + 2 = 29
29 × 9 = 261
This also doesn't match the given options.
Let's assume the correct answer is 60 and work backward. There must be a mistake in the question or provided answer choices. The given substitutions and standard order of operations do not result in any of the choices.
