Mathematics 1 Deneme Sınavı Sorusu #1403049

The total number of students in a class is 45, the number of students passing Mathematics test is 35, the number of students passing Turkish test is 40. If the number of students passing neither Mathematics nor Turkish is 5. Find the number of students passing both Mathematics and Turkish tests.


15

20

25

30

35


Yanıt Açıklaması:

Since the total number of students is 45 then s(M ∪ T) = 45 – 5 = 40. Using the formula

(M ∪ T) = s(M) + s(T) – s(M ∩ T), we have s(M ∩ T) = 35+ 40 – 40 = 35 which is the required number. 

Correct answer is 35.
