Question
The average number of books sold by Viren in first 5
months is 3500 and in first 6 months is 4300. If the number of books sold by him in 7th month is 30% less than that in 6th month, then find the total number of books sold in the seventh month.Solution
Number of books sold by Viren in first 5 months = 3500 × 5 = 17500 Number of books sold by Viren in first 6 months = 4300 × 6 = 25800 Number of books sold by Viren in 6th month = 25800 - 17500 = 8300 Therefore, number of books sold by Viren in 7th month = 8300 × 0.70 = 5810
