Using the principle of proportional relationship, the expected number of doctors which would recommend herbal supplement is 36

Setting up the relationship thus :

2 = 5 doctors

x = 90 doctors

Cross multiply

5x = 90 × 2

5x = 180

x = 180 / 5

x = 36

Therefore, we expect 36 doctors to recommend the supplement out of the 90 employed.
