Question

The number of Computers of Category B is approximately what percent of the total number of Refrigerators?

• A. $29\%$
• B. $31\%$
• C. $37\%$
• D. $43\%$
• E. $47\%$

Answer 1

The correct option is B $31\%$

Total number of products $=900$
Number of Computers $=25$
Number of Televisions $=\frac{1}{3}rdof900=300$
Number of Refrigerators $=32$
$\therefore$ number of Mobile phones $=900-(225+300+288)=900-713=87$
Number of Televisions of Category A $=50$
$\therefore$ number of Televisions of Category B $=300-150=150$
Number of Refrigerators of Category A $=50$
$\therefore$ number Refrigerators of Category B $288-144=144$
Number of Computers of Categories B $=40$
Number of Computers of Category A $=225-90=135$
Number of Mobile phones of Category B $=\frac{1}{3}rdof87=29$
$\therefore$ number of Mobile phones of Category A $=87-29=58$

Number of computers of Category B $=90$
Total number of Refrigerators $=288$
$\therefore$ required percentage $=\frac{90}{288}\times 100\%=31.25\%\approx 31\%$
