Explanation:

Let the profits of CAT and DAT be x, Sales of CAT and BAT be y and sales of ANT be z. So we have

​​​​​​​​​​​​​​

Now, it is said that the total expenses of CAT were Rs.10 lakhs. Thus, 5x = Rs.10 lakhs or x = Rs.2 lakhs. Also, total expenses of ANT were 10% less than those of CAT = Rs.9 lakhs. Hence, 0.9z = 9 lakhs or z = 10 lakhs. Finally, in case of CAT, since Sales – Expenditure = Profit, Sales = Expenditure + Profit = 6x = 12 lakhs, y = 12 lakhs.

Our final table will become:

​​​​​​​​​​​​​​

CAT had highest total expenses i.e., Rs.10 lakhs.
