In Jackson School, 150 students study Spanish or Physics or Both. If 50 of these students do not study Spanish, how many of these students study both Spanish and Physics?
1) Of the 150 students, 30 do not study physics.
2) A total of 120 students study physics

Okay given is that 50 students study just physics, as they are not studying spanish or both physics and spanish.
So looking at statement 1, 30 do not study physics, so they must be studying just Spanish. Therefore 50+30 = 80, the remainder must study both. (70) , so sufficient.
Looking at statement 2, it says a total of 120 students study physics, since the question already gave us that 50 are studying just physics, we have to subtract this from the 120, which gives us 70 that study both spanish and physics, therefore sufficient. Hence answer D
