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.
