Answer & Explanation 1. Answer (D) Required number = (17% of 27300) + (14% of 24700) = 4641 + 3458 = 8099 2. Answer: (D) Required ratio =(21% of 24700)/ (14% of 27300) =(21 x 24700)/(14 x 27300) = 19/14 3. 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. 4. Answer: (D) Required ratio = (21% of 24700)/ (13% of 27300) = 19/13 5. Answer: (C) Required number = (15% of 24700) + (12% of 24700) = 3705 + 2964 = 6669.
