The total revenue generated by all the companies in-2014 is ₹3600 crore.

The revenue of C is 30% of the total revenue = 30% of 3600 crore = 1080 crore.

The revenue generated by A, B and D in the same year is $$\frac{7}{25}, \frac{2}{5}$$ and $$\frac{8}{25}$$ respectively of the remaining revenue

Or the ratio is 7:10:8 of the remaining amount of 2520 crore.

Revenue = Investment (100+profit%)

Revenue of A = (7/25)*2520 = 700 crore approx

Revenue of B = (10/25)*2520 = 1000 crore approx

Revenue of D = (8/25)*2520 = 800 crore approx

Percentage profits of A, B, C and D are 32%,30%,33% and 38%.

Investment of A = 700/1.32 = 530.30 crore

Investment of B = 1000/1.3 = 769.32 crore

Investment of C = 1080/1.33 = 812.03 crore

Investment of D = 800/1.38 = 579.79 crore

C makes the maximum investment in that year.
