A) 185
B) 99
C) 91
D) 119

Correct Answer: B
Solution :
Number of laptops (Dell and Lenovo ) sold by store Q |
\[=4500\times \frac{23}{100}=45\times 23=1035\] |
Now, total number of laptops (Lenovo and Dell) sold by R and S together |
\[=4500\times \frac{46}{100}=2070\] |
Number of Dell laptops sold by R and S together |
\[=2400\times \frac{39}{100}=936\] |
Number of Lenovo laptops \[=2070-936=1134\] |
\[\therefore \] Required difference \[=1134-1035=99\] |
