Correct Answer: 17
Solution :
Given:
If A denotes addition, B denotes multiplication, C denotes subtraction, and D denotes division.
10 B 2 C (15 D 5) = ?
After replacing the letters with symbols, the equation will be as follows –
= 10 × 2 – (15 ÷ 5)
= 10 × 2 – 3
= 20 – 3
= 17
So, after solving the equation the required answer is 17. Hence the fourth option is correct.
