Question

Stiind ca bitdefender a scos la iveala existenta a 40.000 de hibrizi , adica 0,4% din atacurile informatice detectateb, calculati nr acestora.

Answer 1

Notam numarul de hibrizi cu X
Deci avem
$\frac{0.4}{100}*X=40000\Rightarrow X=\frac{400*100*100}{0.4}=\frac{400*100*100*10}{4}=\100*100*100*10=10^{7}=1000000$ sau 10 milioane de atacuri.

Answer 2

0,4/100 •x=40000; x=40000•100/0,4=40000•100/4/10=40000•100•10/4=40000•250=10000000 (x-nr atacuri)
