S11. Ans.(b)

Sol. 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 level in institutes M and S 

= 4641 + 3822 = 8463. 

S12. Ans.(c)

Sol. Required number = (15% of 24700) + (12% of 24700) = 3705 + 2964 = 6669. 

S13. Ans.(d)

Sol. Required number = (17% of 27300) + (14% of 24700) = 4914 + 3458 = 8372.
