What is the total number of 4 star hotels from website A and C together ? 
» Explain it
C
Following the common explanation, we get

Total number of 4 star hotels from Site A and C together are 60

Hence, option C is correct.

Common explanation :

It is given that total number of hotels is 720. 
 
4 star hotels = 2 × (3 star hotels)
 
5 star hotels = 3 × (4 star hotels)
 
Let, 3 star hotels M, 4 star hotels N and 5 star hotels P. 
 
N = 2M
 
P = 3N
 
M + 2M + 6M = 720
 
9M = 720
 
M = 80
 
N = 160
 
P = 480
 
Total 200 hotels listed on sites A. Out of which, 30% are 3 star.
 
60 hotels are there in 3 star category on Site A. 
 
Total 5 star hotels are 480. 
 
Ratio of the hotels on site A, B and C is 1:1:2. 
 
4x = 480
 
x = 120
 
Number of 5 star hotels on B website is 20% more than number of 4 star hotels on the same website.
 
Number of 5 Star Hotels on site B = 120 
 
So, number of 4 star hotels on site B would be 100. 
 
Total 4 star hotels are 160.
 
So 4 star hotels on site C will be 160 – 20 – 100 = 40
 
Number of 3 star hotels on website B and C are same. 
 
Total 80
 
So 3 star and 4 star hotels on site B and C should be 10.
