Question No: 24    ( Marks: 10 )
 The price of medicine inventory is Rs. 500,000.
The series discounts are 20%, 10%, 5%.
What is the single equivalent discount rate?
 if  Invoice was dated May 1st and  10% discount  is offered if invoice is paid up to 10thMay. What will be net payment  for invoice value of Rs. 500,000 if paid up to 10th May.

Solution

List Price=500,000
              D1=20%
              D2=10%
              D3=5%
Net price=N= L (1-d1)(1-d2)(1-d3)
            = 500,000(1-0.20)(1-0.10)(1-0.05)
            = 342,000
Single discounted rate is given by
      Here we see      N=L(1-d)
                          =500000(1-31.6%)
                          =342000
So we can say that …..31.6% is a single discounted rate

Payment over 10th of may= 500,000(1- 10%)
                          = 450,000
