Question

The population of a town is 19128. The number of men and women is 12043, and the men and children is 12571 (a) How many children are there? (b) There are women (c) How many men are there?​

Answer 1

a. Children = 7085

b. Women = 6557

c. Male = 5486

Explanation:

Let's use the following variables to represent the number of children, women, and men in the town:

• C = number of children
• W = number of women
• M = number of men

We know that:

Total population of the town is 19128, and the number of men and women is 12043 and men and children is 12571.

We can also represent this as follows:

• M+W+C = 19128 ... ......[1]
• M + W = 12043 .............[2]
• M + C = 12571 ...............[3]

Substituting the value of equation [2] into the equation [i],

we get:

12043 + C = 19128

Subtracting 12043 in both side, we get

C = 19128 - 12043

C = 7085

Therefore, there are 7085 children.

Again,

We can write equation 1st as :

M + C+ W= 19128

Substituting value of the equation [3] into the equation [i],

12571 + W = 19128

Subtracting 12571 in both side, we get

W = 19128 - 12571

W = 6557

Therefore, there are 6557 Women.

`\hrulefill`

Again,

Substituting value of the W in equation [2], we get

M + 6557 = 12043

Subtracting 6557 in both sides, we get

M = 12043 -6557

M = 5486

Therefore, there are 5486 Male.
