Solution

Number of schools (constructed, destroyed, redeveloped ) in state A = 500 + 250 + 200 = 950 Number of schools(constructed, destroyed, redeveloped ) in state B = 550 + 200 + 300 = 1050 Number of schools (constructed, destroyed, redeveloped ) in state C = 250 + 150 + 400 = 800 Number of schools(constructed, destroyed, redeveloped ) in state D = 300 + 200 + 300 = 800 Number of schools (constructed, destroyed, redeveloped ) in state E = 450 + 100 + 350 = 900 Required average= (950+1050+800+800+900)/5 = 900
