What will come in place of the question mark (?) in the following equation? $4 - 3 \times 6 = ? \times 25 + 160 + 2$

1. 2
2. 1
3. 3
4. 4

Correct answer: 1

Solution

Using order of operations, the left side is $4 - 3 \times 6 = 4 - 18 = -14$. The right side is $? \times 25 + 160 + 2 = 25? + 162$. So $25? + 162 = -14$, giving $25? = -176$, which does not match the options as written; the intended OCR likely has a different arrangement, and the keyed answer is 1.
