marked price of a book is Rs.1000 if shopkeeper gives 2 successive discount 10% and 20% then find selling price of book.
Answers
Answer:
your question is not clear in the terms whether the discount was given together (10% + 20% = 30%) or after the marked price was discounted by 10% then the price which came out as the selling price was again discounted by 20%.
anyways I will tell by both ways
situation one where the discount was added:
discount one = 10%
discount to = 20%
total discount = (10% + 20%) = 30%
selling price = marked price - (total discount × marked price)
= 1000 - (30% × 1000)
= 1000 - (30 × 1000)
100
= 1000 - 300
= 700
therefore, selling price of the book is ₹ 700.
situation two where the marked price is discounted by 10% and then the selling price which is obtained is again discounted by 20%:
discount one = 10%
obtained selling price = marked price - (discount one × marked price)
= 1000 - ( 10% × 1000)
= 1000 - ( 10 × 1000 )
100
= 1000 - 100
= 900
therefore, obtained selling price is ₹ 900
discount two = 20%
final selling price = obtained selling price - ( discount two ×
obtained selling price)
= 900 - ( 20% × 900 )
= 900 - ( 20 × 900)
100
= 900 - 180
= 720
therefore, the final selling price is ₹ 780
this was my explanation.please see to it according to your question which one is right. I have done it either ways it was possible as the question wasn't understood clearly to me.
