6) Answer: c)
Total number of M category flats booked by state A and C together
= > 550 + 600 = 1150
Total number of O category flats booked by state B and E together
= > 1000 + 1100 = 2100
Required % = (1150/2100)*100 = 55 %

8) Answer: d)
The average number of O category flats booked by all the given state people together
= > (850 + 1000 + 900 + 700 + 1100 + 400)/6
= > 4950/6 = 825
