Solutions :
Q1: b
Students of institute M at graduate level = 17% of 27300 = 4641
Students of institute S at graduate level = 14% of 27300 = 3822
So, total number of students at graduate level in institute M & S = 4641 + 3822 = 8463
Q2: c
Required number = (15% of 24700) + (12% of 24700) = 3705 + 2964 = 6669
Q3: d
Required number = (18% of 27300) + (14% of 24700) = 4914 + 3458 = 8372
Q4: d
Required ratio = (21% of 24700)/(14% of 27300) = 19 : 14
Q5: d
Required ratio = (21% of 24700)/(13% of 27300) = 19 : 13
