Answer:

7) 60%

8)1330

9) Base

10) 3/4

Step-by-step explanation:

7) Given: no. of people like pizza A =900

              total no. of people= 1500

FIND:  percentage of people who liked pizza A

           % of people prefer pizza A= 900/1500 X 100

                                                        = 60%

no. of people like pizza B= 1500-900=600

% of people prefer pizza B= 600/1500 X 100= 40%
