Directions for the following 5 (five) items:

Study the two figures given below and answer the five items that follow:

Figure 1: Number of Professors in selected disciplines in a University by sex

Figure 2: Age of Physics Professors

Which one of the following disciplines has the highest ratio of males to females?

Given: 

Table 1:

Table 2:

Calculation:

From Table 1,

The number of male professor in Physics = 32

The number of female professor in Physics = 8 

Now,

Male : Female = 32 : 4

⇒ Male : Female = 4 ∶ 1      ----(1)

The number of male and female professors in Mathematics are 28 and 8 respectively.

⇒ Male : Female = 28 ∶ 8 

⇒ Male ∶ Female = 7 ∶ 2      ----(2)

The number of male and female professors in Chemistry are 16 and 22 respectively.

⇒ Male ∶ Female = 16 ∶ 22

⇒ Male ∶ Female = 8 ∶ 11      ----(3)

The number of male and female professors in Botany are 10 and 14 respectively.

⇒ Male ∶ Female = 10 ∶ 14

⇒ Male ∶ Female = 5 ∶ 7      ----(4)

The number of male and female professors in Psychology are 4 and 6 respectively.

⇒ Male ∶ Female = 4 ∶ 6

⇒ Male ∶ Female = 2 ∶ 3      ----(5)

The number of male and female professors in Economics are 24 and 8 respectively.

⇒ Male ∶ Female = 24 ∶ 8

⇒ Male ∶ Female = 3 ∶ 1      ----(6)

From equations (1), (2), (3), (4), (5) and (6) we can say that physics has the highest ratio of male and female.

∴ Physics disciplines have the highest ratio of male and females.
