Question

Among 300 students in a coaching institute, 180 took
the CAT exam, 150 took the XAT exam and at least
50 students took neither the CAT nor the XAT. If the
number of students who took both the exams is at
least N and at most M, find the value of M + N.

Answer 1

value=330

Step-by-step explanation:

add 180 and 150

I think this could be wrong.

Answer 2

Step-by-step explanation:

180 took CAT concludes 120 didn't took Cat

150 took XAT concludes 150 didn't took XAT

120- 50 equals 70 who took XAT also

150+50 equals 100 who took CAT also

at least 170

180 -70 = 110 only CAT

150-100 = 50 only XAT

160 only took single exam

while 300-160-50 = 90 took both exams
