In a survey of 50 persons of an apartment, it was found that 15 persons read Magazine A, 16 persons read Magazine B, 16 persons read Magazine C, 8 read both A and B, 10 read both Band C, 7 read both C and A and 36 read all three magazines.  How many persons read only Magazine A and B but not C.

Dear student,
your question is incorrect.
You have stated that 36 read all three magazines.
But, 15 persons read Magazine A, 16 persons read Magazine B, 16 persons read Magazine C.
This is not possible, since the number of persons reading all three can not be more than the number of persons reading A,B or C
Kindly, recheck your question and post a correct query in a different thread.

Regards!
