Question

4. At a school fair, 30% of the pies sold had cheese filling, 25% had beef filling and the remaining 90 pies had potato filling. a) The percentage of the pies that had potato filling = %. b) The number of pies sold at the fair - pies. c) How many more cheese pies than beef pies were sold at the fair? more cheese pies were sold than beef pies.​

Answer 1

Explanation:

a) Percentage of potato filling = 100 - (30 + 25) = 100 - 55 = 45 %

b) Let the number of pies sold = x

45% of x = 90

`(45)/(100)*x=90\\\\\\x=90*(100)/(45)\\\\\\x=2*100\\`

Number of pies = 200

c) Number of cheese filling = 30% of 200

`=(30)/(100)*200\\\\= 30*2\\\\\\= 60`

Number of beef pies = 25% of 200

`=(25)/(100)*200\\\\\\=25*2\\\\= 50`

Difference = 60 - 50 = 10

There are 10 more cheese pies than beef pies.
