Question

Shelter A has 500 beds and is 90% occupied. Shelter B is 60% occupied, the ratio of beds in Shelter A to Shelter B is 15:16

Answer 1

Answer:there are 900 beds in shelter B

Explanation:

Shelter A has a capacity of 300 beds and is 80% occupied. This means that the number of beds in Shelter A that would be

80/100 × 300 = 0.8 × 300 = 240 beds.

Let x represent the capacity of Shelter B. Shelter B is 45% occupied. It means that number of beds in Shelter B that would be occupied is

45/100 × x = 0.45 × x = 0.45x beds.

Total occupancy of shelter A and shelter B would be

240 + 0.45x

The ratio of the occupancy of shelter A to shelter B is 16:27

Total ratio of occupancy = 16 + 27 = 43

Therefore

27/43 × (240 + 0.45x) = 0.45x

27(240 + 0.45x) = 0.45x × 43 = 19.35x

6480 + 12.15x = 19.35x

6480 = 19.35x - 12.15x = 7.2x

x = 6480/7.2 = 900

Explanation:

Answer 2

• 800 beds

Explanation:

Shelter A has 500 beds and is 90% occupied.

Number of occupied beds:

• 500*0.9 = 450

The ratio of beds occupied in Shelter A to Shelter B is 15:16

• 450/x = 15/16
• x = 450*16/15
• x = 480

Number of occupied beds in Shelter B is 480 which is 60% of total. Total number of beds is:

• 480/0.6 = 800
