In the figure given below, the three circles show the visitors to a canteen who ordered tea, coffee and juice; each number is the number of visitors in that region.
How many visitors ordered at least two of the three drinks?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 17
‘At least two’ means two or three drinks, so every region shared by two circles is counted, and the region shared by all three circles as well.
Tea and coffee only: 7
Tea and juice only: 3
Coffee and juice only: 5
All three drinks: 2
Total \(=7+3+5+2=17\)
