• question_answer The difference between a discount of 35% and two successive discounts of 20% and 20% on a certain bill was Rs 22. Find the amount of the bill. A)  Rs 3200            B)         Rs 2200            C)         Rs 1800            D)         None of these

The equivalent discount of two successive discounts of 20% and 20% $=\,\left( x+y+\frac{xy}{100} \right)%$ $=\,\left( -20-20+\frac{20\times 20}{100} \right)%\,\,\text{or}\,-36%$ Given, 36%-35% = Rs 22 Let the amount be $x$. then,         1% of $x=22$ $\frac{1\times x}{100}=22$ $x=\text{Rs}\,\,2200$ $\therefore$ Amount of the bill = Rs 2200
