Answers
Given : number of Burgers and Pastries sold by each of the three
shopkeepers D, E, and F
To Find : Data for Each each shopkeeper
Solution:
Let say burgers sold by D = B
The number of pastries sold by F is 250 more than the number of burgers sold by D.
The number of pastries sold by F = 250 + B
burgers sold by E is 20% more than that of D
The number of burgers sold by E = B + (20/100)B = 1.2B
the ratio of pastries sold by D to the number of burgers sold by E
Pastries Sold by D = (7/6) 1.2B = 1.4B
The number of burgers sold by F is 1050
The total number of paistries sold by all the three shopkeepers is 2700.
pastries sold by F = 250 + B
Pastries Sold by D = 1.4B
=> Pastries Sold by E = 2700 - ( 250 + B + 1.4B) = 2450 - 2.4B
burgers sold by E = 1.2B
Total number of items sold by E is 1550
2450 - 2.4B+ 1.2B = 1550
=> -1.2B = 900
=> B = 750
burgers sold by D = B = 750
burgers sold by E = 1.2B = 900
number of burgers sold by F is 1050
pastries sold by F = 250 + B = 1000
Pastries Sold by D = 1.4B = 1050
Pastries Sold by E = 2450 - 2.4B = 650
