Question
What is the ratio of total number of refrigerators in
Store B and D together to the total number of AC in the same Store together? Study the table carefully to answer the questions given below: Total number of items = 32500 The items are sold in various store and within each store percentage of refrigerators and AC is given.Solution
Total number of Refrigerators in B = (15/100) × 32500 × (60/100) = 2925 Total number of Refrigerators in D = (28/100) × 32500 × (75/100) = 6825 Total number of AC in B = (15/100) × 32500 × (40/100) = 1950 Total number of AC in D = (28/100) × 32500 × (25/100) = 2275 Required Ratio = (2925 + 6825): (1950 + 2275) => 9750 ∶  4225 = 30∶ 13
