Given that 4 people would not <span>go to a park or a beach or a cottage.
Number of people that will </span><span>go to neither a park nor a cottage but will go to a beach = 5 - 4 = 1.
</span><span>Number of people that will <span>go to neither a beach nor a cottage but will go to a park = 9 - 4 = 5
</span></span>
<span>Number of people that will <span>go to neither a park nor a beach but will go to a cottage = 8 - 4 = 4
</span></span>
Number of people that will not go to a cottage but will go to a beach or a park = 12 - 5 - 1 = 6
Number of people that will not go to a beach but will go to a cottage or a park = 10 - 5 - 4 = 1
Number of people that will not go to a park but will go to a beach or a cottage = 12 - 4 - 1 = 7
Number of people <span>willing to go to all three places = 5
Therefore, total number of colleagues = 4 + 1 + 5 + 4 + 6 + 1 + 7 + 5 = 33
