What is the difference between the average number of schools redeveloped and the number of schools destroyed in all the states together?
Average number of schools redeveloped in all the states together = (200+300+400+300+350)/5 = 310 Average number of schools destroyed in all the states together = (250+200+150+200+100)/5 = 180 Required difference = 310 – 180 = 130
