Q8. Which among the following states has to construct maximum houses in all the given years together?
UP: (10 + 20 + 25 + 40 + 40 + 60 + 50) 1000 = 2,45,000
MP: 5,500 + 20,000 +18,000 + 25,000 +25000+ 30,500 + 40,000 = 1,64,000
HP: 2,000 + 5,000 + 5,000 + 10,000 + 5,000 + 15,000 + 20,000 = 62,000
Gujarat: 12,000 + 10,000 + 15,000 + 15,000 + 20,000 + 15,000 + 20,500 = 1,07,500
