Concept:Use BODMAS rule: solve Brackets first, then Multiplication, then Addition and Subtraction from left to right.Explanation:First, solve the bracket: 93+14=107.Next, do multiplication: 56×2=112.Now the expression is: 107−112+33+15.Group positive terms: 107+33+15=155.Finally subtract: 155−112=43.Answer:43 (Option A)
