The arithmetic mean (average) of a set of 10 numbers is 10. Is the median value of the same set also equal to 10?

1. Exactly half of the numbers are less than 10.
2. The mode of the set of numbers is 10.

Sum/10=10

Sum=100

Median=(5th+6th term)/2

stmt1,

5 numbers are less than 10

Either 5th term or 6th term are less than 10

Insuff

stmt2,

Mode=10

Either 5th or 6th term is 10

Combining 1 and 2

Median=(5th term+6th term)/2<10 as one term is less than 10

Pick C
