Question : Directions: If A denotes addition, B denotes multiplication, C denotes subtraction, and D denotes division, then what will be the value of the following expression? 35 B 2 A 5 B (40 C 37) A (8 B 4) D 16 C 14 = ?
Option 1: 66
Option 2: 54
Option 3: 73
Option 4: 56
Correct Answer: 73
Solution : Given: 35 B 2 A 5 B (40 C 37) A (8 B 4) D 16 C 14 = ?
On replacing the letters with the mathematical signs as per the instructions given in the question, we get – = 35 × 2 + 5 × (40 – 37) + (8 × 4) ÷ 16 – 14 = 35 × 2 + 5 × 3 + 32 ÷ 16 – 14 = 35 × 2 + 5 × 3 + 2 – 14 = 70 + 15 + 2 – 14 = 87 – 14 = 73
So, 73 is the required answer. Hence, the third option is correct.
