a. 8
b. 6
c. 4
d. 2​

Answer 1

Hey MATE!!!

Let us assume the number to be x.

Therefore, from the given condition we get that;

${ \frac{x}{2} }^{2} - x = 48 \\ \\ \frac{ {x}^{2} }{4} - x = 48 \\ \\ {x}^{2} - 4x = 192 \\ \\ {x}^{2} - 4x - 192 = 0 \\ \\ {x}^{2} - 16x - 12x - 192 = 0 \\ \\ (x + 12)(x - 16) = 0 \\ \\ x = - 12 \: \: or \: x = 16$

Hope it helps
