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 \[=1134-1035=99\] |
