The Correct Option is D
Solution and Explanation
1. Step 1: Break down the operations
- The symbol \( \oplus \) means subtraction (“-”).
- The symbol \( \otimes \) means multiplication (“:”), so \( 4 \otimes 2 = 4 \times 2 = 8 \).
- The symbol \( \nabla \) means multiplication (“×”), so \( 8 \nabla 4 = 8 \times 4 = 32 \).
- The symbol \( \Delta \) means addition (“+”).
2. Step 2: Evaluate the expression
We now substitute the values into the expression: \[ \Delta 2 \oplus 3 \Delta (32) \] This becomes: \[ 2 + 3 - 32 = 7 \] Thus, the value of the expression is 7. Final Answer: (D)
