Question

The difference between a discount of $35\%$ and two successive discounts of $20\%$ on a certain bill was $22$. Find the amount of the bill.

• A. $200$
• B. $1100$
• C. $2200$
• D. $1000$

Answer 1

The correct option is C $2200$

Let the bill amount be 100.
One discount $=35$
Two successive discounts $(100-\frac{100\times 80\times 30}{100\times 100})(100-64)=36$
Difference $=36-35=1$
If the difference is 1, the bill amount is 100.
If the difference is 22, the bill amount will be $22\times 100=2200$.
