An article is marked at 5,000. The shopkeeper allows successive discounts of x%, y%, z% on it. The net selling price is
Marked price = 5,000
Successive discounts of x% , y% and z% are allowed on it
=> S.P. = $$5000 \times \frac{(100 - x)}{100} \times \frac{(100 - y)}{100} \times \frac{(100 - z)}{100}$$
= $$\frac{(100-x)(100-y)(100-z)}{200}$$
