Question
The average number of books sold by Viren in first 4
months is 3200 and in first 5 months is 4300. If the number of books sold by him in 6th month is 20% less than that in 5th month, then find the total number of books sold in the sixth month.Solution
Number of books sold by Viren in first 4 months = 3200 × 4 = 12800 Number of books sold by Viren in first 5 months = 4300 × 5 = 21500 Number of books sold by Viren in 5th month = 21500 - 12800 = 8700 Therefore, number of books sold by Viren in 6th month = 8700 × 0.80 = 6960
