Question 1
How many students of institutes M and S are studying at graduate level ?
Correct Answer: Option B
Students of institute M at graduate level :
Total number of students at graduate in institute M and S
= 17% of 27300 = 4641
Students of institute S at graduate level :
= 14% of 27300 = 3822
Total number of students at graduate in institute M and S= (4641 + 3822) = 8463
Question 2
What is the total number of graduate and post-graduate level students in institute R ?
Correct Answer: Option D
Required number
= (17% of 27300) + (14% of 24700)
= 4641 + 3458
