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? 15 B (14 C 7) A 25 D (18 C 13) C 8 B (2 A 3) =?
Option 1: 105
Option 2: 115
Option 3: 70
Option 4: 40
Correct Answer: 70
Solution : Given: A denotes addition, B denotes multiplication, C denotes subtraction, and D denotes division. 15 B (14 C 7) A 25 D (18 C 13) C 8 B (2 A 3) =?
After replacing letters with equivalent symbols, the equation becomes – = 15 × (14 – 7) + 25 ÷ (18 – 13) – 8 × (2 + 3) = 15 × 7 + 25 ÷ 5 – 8 × 5 = 105 + 5 – 40 = 70
So, after solving the equation the answer is 70. Hence, the third option is correct.
