• A. 225
• B. 323
• C. 325
• D. 223
• E. None of these

Answer 1

The correct option is B 323

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 $=87-29=58$

Required value $=NumberofTelevisionsofCategoryA+NumberofRefrigeratorsofCategoryB+NumberofMobilephonesofcategoryB=150+144+29=323$
