• D. 52, 60, and 72

Answer 1

The correct option is B 52, 60, and 67

Following the key, the above stem and leaf diagram can be read as:
50, 52, 52, 55, 58, 60, 60, 62, 63, 67, 67, 70, 71, 72

To find the mode of the given data, we first arrange it into an ordered list of the marks and the frequencies of their occurrence:

50	52	55	58	60	62	63	67	70	71	72
1	2	1	1	2	1	1	2	1	1	1

Thus, the modes of the given data are 52, 60, and 67.
