Answer 2

Given,

The ratio of doctors to lawyers = 5:4

Total number of people in the group = 72

To find,

The number of doctors in the group.

Solution,

The number of doctors in the group will be 40.

We can easily solve this problem by following the given steps.

According to the question,

The ratio of doctors to lawyers = 5:4

Total number of people in the group = 72

Let's take the number of doctors to be 5x and the number of lawyers to be 4x.

Then,

(5x+4x) = 72

9x = 72

x = 72/9

x = 8

So,

Number of doctors = 5x

Number of doctors = (5×8)

Number of doctors = 40

Number of lawyers = 4x

Number of lawyers = (4×8)

Number of lawyers = 32

Hence, the number of doctors in the group is 40.
