Question

The difference between the discounts of $40\%$ on Rs. $5000$ and two successive discounts of $36\%$ and $4\%$ on the same price is :

• A. Rs. $62$
• B. Rs. $72$
• C. Rs. $19.3$
• D. Rs. $20$

Answer 1

The correct option is B Rs. $72$

Single equivalent discount of two successive discounts of $36\%$ and $4\%:$

$\Rightarrow$ $36+4-\frac{36\times 4}{100}=40-1.44=38.56\%$

Percentage difference $=$ $(40-38.56)\%=1.44\%$

Thus required difference $=$ $5000\times \frac{1.44}{100}=$ Rs. $72$
