the answer is A
mean will take more time to calculate than median so the median will be 5+7/2=6 the only one option which has median as 6 so a is the answer

(E) 8.5, 9.5


With the same approach as nks2611

Median of the given data will be \(\frac{( 5 + 7 )}{2} = 6\)

Thus, answer must be (A) 6.5, 6
