Question

Find the successive discount equivalent to $10\%$ and $5\%$.

• A. $14.5\%$
• B. $15\%$
• C. $15.5\%$
• D. $16\%$

Answer 1

Answer: (A)

$14.5\%$

Let price of a product be $100$

It is subjected to two successive discounts $10\%$ and $5\%$

$\therefore$ Final price of product $=\frac{100-10}{100}\times \frac{100-5}{100}\times 100$

$=85.5=100-\frac{14.5}{100}\times 100$

$\Rightarrow$ Successive discounts of $10\%$ and $5\%$ equal to a discount of $14.5\%$
