Upper primary school mathematics question UPQ588
The pie chart below shows the type of buns sold at a shop last week. The shop sold 900 buns in all. Half of the buns sold were chocolate. The shop sold 20% more cheese buns than vanilla buns.
a. How many banana buns did the shop sell?
b. What percentage of the buns sold last week were cheese buns?
a. 100% ==> 900
1% ==> 9 buns
17% ==> 9 × 17 = 153 buns
The number of Banana buns = 153
b. Total percentage of Cheese buns and Vanilla buns
= 50% – 17%
33% ==> 33 × 9 = 297
The ratio of cheese buns to vanilla buns = 120 : 100 = 6 : 5
11 units = 297
1 unit = 27 buns
The number of cheese buns sold
= 6 × 27
The percentage of cheese buns sold
= 162 ÷ 900 × 100%
