30% of those who had a hot drink at morning
tea time in a large factory had a cup of tea.
40% of 30% had milk in their tea, so
12% of those who had a
hot drink had tea and milk in their tea
----------------------------------
4% of those who had a hot
drink had tea, had milk in their tea, and had sugar, as well
--------------------------
150 people at the factory had a hot drink at morning tea time
Let = the number of people in this last group, so
6 people had milk and sugar in their tea
Hope this helps
