500 shoppers at a Lucknow mall were asked whether they used the food court, the cinema, both or neither, and the diagram gives percentages. How many shoppers used both?

Question

Accepted Answer

75. The four parts add to 100%: 38 + ? + 27 + 20 = 100, so both = 15\%, and 15% of 500 is 75. 100 is the 20% who used neither, 175 is 35\% (forgetting the neither part), and 400 is the 80% who used at least one.
