• A. 146
• B. 176
• C. 167
• D. 156
• E. None of these

Answer 1

The correct option is E None of these

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 Mobile phones of Category B $=229$
Total number of Computers $=225$
$\therefore$ required difference $=225-29=196$
