Answer 2

Answer:  The correct options is

(c) 26.

Step-by-step explanation:  Given that the product of two numbers is 1856 and their sum is 90.

We are to find the difference of the two numbers.

Let x and y represents the given numbers.

Then, according to the given information, we have

$xy=1856,\\\\x+y=90.$

We will be using the following formula :

$(a-b)^2=(a+b)^2-4ab.$

We have, for x and y,

$x-y\\\\=\sqrt{(x+y)^2-4xy}\\\\=\sqrt{90^2-4\times1856}\\\\=\sqrt{8100-7424}\\\\=\sqrt{676}\\\\=26.$

Thus, the required difference of the two numbers is 26.

Options (c) is CORRECT.
