B 50
C 30
D none of these

Answer 1

To find the mode of the data set, we need to identify the number that appears most frequently.

The data set is:
70, 80, 50, 30, 40, 50, 90, 80, 50

Now, let's count the frequency of each number:
- 30: 1 time
- 40: 1 time
- 50: 3 times
- 70: 1 time
- 80: 2 times
- 90: 1 time

The number that appears most frequently is 50, which occurs 3 times.

So, the mode of the data set is 50.

The best answer is: **B 50**.
