127. In Jefferson School, 300 students study French or
Spanish or both. If 100 of these students do not study
French, how many of these students study both French
and Spanish?
(1) Of the 300 students, 60 do not study Spanish.
(2) A total of 240 of the students study Spanish.

Guys i solved this question using double set matrix
French Not French Total
Spanish x=? 100 240
Not Spanish 60
300

1)
French Not French Total
