Solutions (91-95)
Total Profit = 60 Crore
According to Qs:
Profit of Company B is 20% of the Income of Company C
Let Income of Company C is P
So P x 20% = 16
P = (16 * 100)/100 = 80 Cr.
Income of Company C = 80 Cr
Profit of Company B is also equal to 40% of the Expenses of Company A
Let Expense of Company A is P
So P x 40% = 16
P = (16 * 100)/40 = 40 Cr
Expense of Company A = 40 Cr
