Answer 2

According the question,Out of 70 students in a class, 30 students study German, 40 students study french and 50 students study Italian.

The number of students present in the class = 70        ( given)

Total number of students who study German = 30                ( given)

Total number of students who study French = 40                 ( given)

Total number of students who study Italian = 50                  ( given)

Therefore the total number of students who study all the three languages are = ( 30 + 40 + 50 + ) - 70 =( 120 - 70 ) = 50

Hence , there are 50 students who study all the three languages.
