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?
50 D (2 B 5) A 3 B (15 A 12) C 2 B (18 C 15) =?
Option 1: 54
Option 2: 127
Option 3: 80
Option 4: 89
Correct Answer: 80
Solution :
Given:
A denotes addition, B denotes multiplication, C denotes subtraction, and D denotes division
50 D (2 B 5) A 3 B (15 A 12) C 2 B (18 C 15) =?
After replacing the letters with the mathematical signs, the equation becomes –
50 ÷ (2 × 5) + 3 × (15 + 12) – 2 × (18 – 15)
50 ÷ 10 + 3 × 27 – 2 × 3
5 + 3 × 27 – 2 × 3
5 + 81 – 6
= 80
So, the given equation is equal to 80. Hence, the third option is correct.
