Answer:
Given:
There are 240 doctors and nurses in a hospital.
Ratio of doctors to nurses is 5:7
Solution:
Ratio of doctors to nurses = 5:7
Total = 5 + 7 = 12
Total number of doctors and nurses = 240
Therefore;
Number of doctors = 5/12 × 240
= 100
Number of nurses = 7/12 × 240
= 140
Alternative way:
Ratio of doctors to nurses = 5:7
Let the number of doctors and nurses be 5x and 7x respectively.
Therefore, ATQ.
5x + 7x = 240
=⟩ 12x = 240
=⟩ x = 240/12
=⟩ x = 20
Now,
Number of doctors = 5x
= 5 × 20
= 100
Number of nurses = 7x
= 7 × 20
= 140
Summary:
Given ratio = 5:7
Total doctors and nurses = 240
Number of doctors = 100
Number of nurses = 140
Hope this was helpful, cheers:)
