Question

150 students take tea 225 take coffee 100 take both tea and coffee. Find out how many students take coffee and not tea.

Answer 1

Answer:

n ( taking tea) = 150

n (taking coffee) = 225

n ( taking both ) = 100

n(people taking tea or coffee) = n ( taking tea) +  n (taking coffee) -  n ( taking both )

                                                = 150 + 225 - 100

                                                =375 - 100  

                                               = 275

Total students = 600

n(students  taking neither tea nor coffee ) = 600 - 275 = 325

Hence,325 students were taking neither tea nor coffee.
