The Correct Option is C

Solution and Explanation

First, simplify the fraction: \[ \frac{120}{240} = 0.5 \] Now, \[ 5 + 12 \times 10 \times 0.5 = 5 + 12 \times 5 \] \[ = 5 + 60 = 65 \] We have: \[ 65 = A \times 10 \Rightarrow A = \frac{65}{10} = 6.5 \] Wait — this suggests a mismatch, so check the original order of operations: If it’s \( 5 + 12 \times 10 \times \frac{120}{240} \), then: \[ 12 \times 10 = 120, 120 \times 0.5 = 60, 5 + 60 = 65 \] Thus, \[ 65 = A \times 10 \Rightarrow A = 6.5 \] Hence, the correct value is \( \boxed{6.5} \).
