Percentage wise Distribution of laptops (Dell & Lenovo) sold by six stores A, B, C, D, E and Fin March 2014.
Total No of Laptops (Dell and Lenovo) sold = 48000
No of Dell Laptop sold = 28000
Percentage of dell laptop sold
Solution
Number of laptops of both kinds sold by store A = $$\frac{18}{100} \times 48000$$
= $$18 \times 480 = 8,640$$
Number of Dell laptops sold by store A = $$\frac{14}{100} \times 28000$$
= $$14 \times 280 = 3,920$$
=> Lenovo laptops sold by store A = $$8,640 - 3,920 = 4,720$$
$$\therefore$$ Required ratio = 3920 : 4720
= 49 : 59
