GRADE 12 - MATHEMATICS PAPER 2 - St Stithians College

QUESTION 13
The Dainfern College tuck shop sells three kinds of pizzas; Hawaiian, Salami and Tikka Chicken.
Mr Atteridge, who has a passion for statistics (and pizzas), produces the following report:
“During the past month, the Hawaiian pizzas were most popular and accounted for 40% of the
total number of pizzas sold. Of the remainder, 40% were salami. The range of the total number
of pizza sold was 128. The popularity of the Hawaiian pizzas was exaggerated because of the
Derby Day on which 59 more Hawaiian pizzas were sold than any other kind. This was probably
due to the Hawaiian pizzas being sold half-price.”
a) How many Tikka Chicken pizzas were sold? (4)
b) If you ignore the 59 pizzas sold at half-price, what is the range of the total number of
each kind of pizza sold? (3)
