Question

In a factory, there are $1000$ workers out of which $400$ are men and $100$ are married. Out of $600$ women, $300$ are married. Tabulate this data and calculate the total number of unmarried workers.

• A. $400$
• B. $600$
• C. $700$
• D. $800$

Answer 1

The correct option is B $600$

	Married Workers	Unmarried Workers
Men	$100$	$x$
Women	$300$	$y$

Total number of men $=400$

$\therefore 100+x=400$

$x=300$

Total number of women $=600$

$\therefore 300+y=600$

$y=300$

Total number of unmarried workers $=x+y=600$
