x = y - (40/y), where x and y are both > 0. If the value of y is doubled in the equation above, the value of x will
Choose the correct choice from the following answers.
A) decrease	B) stay the same	C) increase four fold	D) double	E) Triples
Alternate approach   Plug in some values of y &gt; 0   Let y = 10   So, x = y - (40/y)   Or, x = 10 - (40/10)=

6   Let y= 20   So, x = y - (40/y)   Or, x = 20 - (40/20)=

<output>18</output>
18   So, x increases from 6 to 18   Hence the number increases 3 times, thus the correct answer will be (Triples)
