Explanation:

From I: Ratio of investment = A:B:C = 4800:4000:3600
= 12:10:9
Ratio of profit share = A:B:C = (12*12): (10*12) : (9*9) = 48:40:27
Profit of C = 27/(48+40+27)*4600 = Rs.1080
From II: Difference between the compound interest and simple interest for 2 years.
CI – SI = P * (R/100)^2
=> P = Rs.1500
I < II

Hence, option 5 is the correct answer.
