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.
