There are two kinds of MBA exams CAT and MAT. 1/3 students did not get good score in CAT and 1/2 students did not get good score in MAT. 60% students who aced CAT also aced MAT. If 300 students sat for both the exams, then how many students did not get a good score in both CAT and MAT?
Answers
Answer:
CAT
Students who did not score well = 100
Students who scored well = 200
MAT
Students who did not score well = 150
Students who scored well = 150
Students who scored well in both exams = 60% * 150
= 90
B= 90
A= 200-90
=110
C= 150-90
=60
Students who scored well in at least one = 110 + 90 + 60 = 260
Students who failed in both = 300 - 260 = 40

Step-by-step explanation:
CAT
Students who did not score well = 100
Students who scored well = 200
MAT
Students who did not score well = 150
Students who scored well = 150
Students who scored well in both exams = 60% * 200
= 120
B= 120
A= 200-120
=80
C= 150-120
=30
Students who scored well in at least one = 120 + 80 + 30 = 230
Students who failed in both = 300 - 230 = 70
