Find a single discount equivalent to two successive discounts of 15 percent and 5 percent.

Correct option is A

Given:

2 successive discounts of 15% and 5%.

Formula Used:

Effective discount for a% and b% discounts

= a% + b% - ($$\frac{ab}{100}$$​)%

Solution:

Effective discount for 15% and 5% discounts:

= $$15\% + 5\% - \left\{ \frac{15 \times 5}{100} \right\}\% = 20\% - 0.75\% = 19.25\%$$​​
