Correct answer: 48
Solution
Given, be two number where .
The geometric mean of these numbers exceeds the smaller number by .
i.e. .....(i)
And the arithmetic mean of the same numbers is smaller by than the number .
i.e. ......(ii)
By solving Equations. (i) and (ii), we get
The geometric mean of these numbers exceeds the smaller number by .
i.e. .....(i)
And the arithmetic mean of the same numbers is smaller by than the number .
i.e. ......(ii)
By solving Equations. (i) and (ii), we get
Hence, the correct answer is 48.
