Step-by-step explanation:

Answer 2

Given:

There were 200 employees in an office in which 150 were married. Total male employees were 160 out of which 120 were married.

To find:

The number of female unmarried employees.

Solution:

The correct option is b) 10.

To answer this question, we will follow the following steps:

As given, we have,

Total number of employees in an office = 200

The number of employees that were married = 150

So,

The number of unmarried employees = 200 - 150 = 50

Also given,

The number of male employees = 160

So,

The number of female employees

$= 200 - 160 = 40$

Out of 160 male employees, the number of male employees that were married = 120

So,

The remaining number of married employees that must be females = total married employees - total male married employees

$= 150 - 120$

$= 30$

So,

The number of unmarried female employees

= total female employees - married female employees

$= 40 - 30$

$= 10$

Hence, the total number of unmarried female employees is 10.
