- A. 40
- B. 35
- C. 30
- D. None of these
C. 30
Answer: 30
Explanation :
we need to multiply the first number (3) by the alternate number (5). thus, (3∆5) is equal to 3 multiplied by 5, which equals 15. Next, we've to calculate(15∆2) using the same note.
Again, we multiply the first number (15) by the alternate number (2) to get the result. thus,(15∆2) is equal to 15 multiplied by 2, which equals 30. thus, the answer is 30. We can represent the entire expression using the accurate note as follows (3∆5)∆2 = (3x5)∆2 = 15∆2 = 15 x 2 = 30 So, the final result of the expression(3∆5)∆2 using the given note is 30.
