Answer:

27

Explanation:

Given :

Total number of people : 36

Ratio of people who prefer red to blue

Red : Blue = 3 : 9 = 1 : 3

according to the ratio, for every 4 people, 1 prefers red and 3 prefers blue.

Expressed mathematically:

People who prefer blue = 3/4 of the total number of people

In our case, total number is 36 hence,

People who prefer blue (and hence the number of blue pens he should order),

= 3/4 x 36 = 27
