• A. 110.25
• B. 115.5
• C. 121.75
• D. 102
• E. 106

Answer 1

The correct option is C 121.75

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 $=87-29=58$

Total number of products of Category A $=150+144+135+58=487$
$\therefore$ required average $=\frac{487}{4}=121.75$
