6.    Answer  (D)

Required number = (17% of 27300) + (14% of 24700)

= 4641 + 3458

= 8099

7.    Answer: (D)

Required ratio =(21% of 24700)/ (14% of 27300)

=(21 x 24700)/(14 x 27300) = 19/14

8.    Answer: (B)

Students of institute M at graduate level= 17% of 27300 = 4641.

Students of institute S at graduate level = 14% of 27300 = 3822.

Total number of students at graduate in institutes M and S = (4641 + 3822)

= 8463.

9.    Answer: (D)

Required ratio = (21% of 24700)/ (13% of 27300)

= 19/13

10.  Answer: (C)

Required number = (15% of 24700) + (12% of 24700)

= 3705 + 2964

= 6669.
