Answer & Explanation
Answer (1 – 5):
Therefore, second highest number of books sold was of Reasoning.
We need to check for which shopkeeper (s) the number of General Awareness books sold were the highest, for that shopkeeper the percentage of General Awareness books sold as a percentage of total number of books sold by that shopkeeper would be higher than for the shopkeeper who has not sold maximum number of General Awareness books out of all the books sold, there is only one shopkeeper i.e. D
Required average = (27 + 29 + 31)/3 = 29 => 29,000
Number of Reasoning books returned = 18% of 4000 = 720
required percentage = 720/31000 * 100 = 2.32%
Number of General Awareness books returned = 780
total number of books returned = 780/13% = 6000
Number of English and Banking Awareness books returned = 37% of 6000 = 2220
Required ratio = 46000:2220 = 2300:111≈ 41:2
