Answer: a. 55

Explanation:

The formula to find the geometeric mean between two numbers a and b is given by :-

G.M. =√(ab)

The given numbers are : 275 and 11

The geometric mean of 275 and 11 is given by :-

$G.M.=√(275*11)\\\\\Rightarrow\ G.M. =√(3025)\\\\\Rightarrow\ G.M.=√(55*55)\\\\\Rightarrow\ G.M.=√(55^2)\\\\\Rightarrow\ G.M.=55$

Hence, the geometric mean of 275 and 11 is 55.

So , the correct option is a. 55 .
