Sales of books from four shops (B1, B2, B3, B4) in thousands are given as below. Study the graph and answer the following questions. If each shop can increases the sales of books by 10%,then the total number of books(in thousands) soldby all the shop are:
214.5
Given:
each shop can increases the sales of books by 10%.
Formula used:
total value of things after percent increment = old value × (100 + increment%)/100
Calculation:
Before increment number of books in different shops(in thousands) are following -
Number of books in B1 shop = 20
Number of books in B2 shop = 40
Number of books in B3 shop = 55
Number of books in B4 shop = 80
After increment number of books in different shops(in thousand) are following -
Number of books in B1 shop = 20 × 110/100 = 22
Number of books in B2 shop = 40 × 110/100 = 44
Number of books in B3 shop = 55 × 110/100 = 60.5
Number of books in B4 shop = 80 × 110/100 = 88
Sum of total books after increment in all shops = 214.5 (in thousands)
∴ After increment number of books in different shops(in thousand) are 214.5 thousands.
