From the original condition

Revenue-Expense=Profit

$$Revenue_A-Expense_A=Profit_A$$
$$Revenue_B-Expense_B=Profit_B$$

$$\frac{(Profit_A-Profit_B)}{Profit_B}$$·100

1) $$Revenue_A=1.1Revenue_B$$
Insufficient

2) $$Profit_B$$=50
Insufficient

Together,
$$Revenue_A-Expense_A=Profit_A$$
$$1.1Revenue_A-Expense_B=50$$

But we don't know the ratio of expenses.
