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 $
