indroid platform in 2015. What was the percent
change from 2014 to 2015 in the number of
downloads on android platform for the app ‘A’?

Answer 1

Hey it's too simple dear

100% of 200 = 200

40% of 600 = 40/100 * 600 =240

Percent change is -

Change in number of downloads on Android platforms /change in total number of downloads * 100

= (240 - 200) /(600 - 200) *100

=10%
