Answer 2

Answer:

The number of guests took black coffee with neither milk nor sugar is equal to 9.

Step-by-step explanation:

Given, the total number of guests in the conference room =144

The number of guests took coffee with sugar only $=\frac{144}{4}=36$

The number of guests took both milk and sugar $=144*\frac{5}{8}=90$

The number of guests took only milk $=\frac{1}{16}*144=9$

The number of guests took black with neither milk nor sugar will be:

$= 144 - (36+90+9)$

$=144-135$

$=9$

Therefore, the number of guests took black with neither milk nor sugar will be 9 guests.
