Question
The table given below shows the percentage of number of
Laptop's sold by five different companies namely 'A', 'B', 'C', 'D' and 'E', out of total number of Laptop's manufactured by each of the five companies. Suppose the number of laptops sold by Company 'B' is 20% more than that by Company 'D', then the number of laptops manufactured by Company 'D' is what % of the number of laptops manufactured by 'B'.Solution
ATQ, Let number of laptops sold by Company 'D' be '100x'. So, number of laptops sold by Company 'B' = 1.2 X 100x = '120x' Number of laptops manufactured by Company 'D' = 100x ÷ 0.80 = '125x' Number of laptops manufactured by Company 'B' = 120x ÷ 0.60 = '200x' Therefore, required % = (125x/200x) X 100 = 62.5%
