Find the effective price percentage of the marked price after three consecutive discounts of 8%, 17% and 17%. (Rounded up to two decimal places.)​

Correct option is C

Given:

Three consecutive discounts of 8%, 17%, and 17%.

Formula Used:

The price after consecutive discounts is:

Effective Price = Marked Price$$\times (1 - \frac{d_1}{100}) \times (1 - \frac{d_2}{100}) \times (1 - \frac{d_3}{100})$$​​

Where $$d_1, d_2, d_3$$​ are the percentages of the three discounts.

Solution:

Let the MP be 100 

So, 

Effective Price = $$100 \times \frac{92}{100}\times \frac{83}{100}\times \frac{83}{100}$$

= 63.38 

Price in percentage = $$\frac{63.38}{100}\times 100 = 63.38\%$$​​
