Question 5: Marks 0 Find amount of markup and selling price on an item that costs Rs. 2400 if there is a 40% markup on cost.
Solution:
Rs Markup = %Markup on cost × Cost price Rs Markup = (.40) (2400)
Rs Markup = 960
Selling Price
Then the selling price, being the cost plus markup, that is:
Selling Price = Cost price + Rs Markup
Note: Solve these papers by yourself
Selling price= 2400 + 960 = 3360
Question 6: Marks 0
An item sells for Rs. 3200. If the markup on the cost is 48%, find the cost and the amount of the markup.
Selling Price = Cost price + (Cost price × %Markup on cost)
Selling price = Cost price (1 + %Markup on cost)
3200 = Cost price (1 + 48%)
3200 = Cost price (1.48) Cost price = 3200/Cost price = 216Rs Markup = %Markup on cost × Cost price
Rs Markup = (.48) (2162)
Rs Markup = 1038
Question 7: Marks 0 Find the single discount rate that is equivalent to the series discount of 5%, 7% and 11%.
Let list price = 100
Series trade discount: Net price = List price(1-d1)(1-d2)…..(1-dn) = 100 (1 - .05)(1 - .07)(1 - .11)
= 100(.95)(.93)(.89) =100(.786315) =78.63
Single discount rate = 100 – 78.63
= 21.37%
Question 8: Marks 05
An item that cost Rs. 2300 was marked up 38 % of the selling price. After some time the item is markdown 30 %. Calculate the sale price after markdown.
Solution:
Check handouts page number 122 lectures 16….Example given
Original Sale Price
Let Selling price = 100 %Markup on selling price = 45% Cost = 100 – 45 = 55
Thus Original Sale price = (100/55) x 57.75 = 105Rs
Rs. Markdown
%Markdown = 40% = 0.4
Rs. Markdown = 105 x 0.4 = 42
Sale price after markdown
Sale price after markdown = 105 – 42 = 63 Rs
Q # 8
An item that cost Rs. 2300 was marked up 38 % of the selling price. After some time the item is markdown 30 %. Calculate the sale price after markdown.
Cost=2300
Marked up=38%
So
(2300)(0.38)=874
2300+874=3174
Now
Cost=3174
Mark down=30%
(3174)(0.30)=952.2
3174-952.2=2221.8
Selling price=2221.8
Cost=2300
Marked up=38%
So
(2300)(0.38)=874
2300+874=3174
Now
Cost=3174
Mark down=30%
(3174)(0.30)=952.2
3174-952.2=2221.8
Selling price=2221.8
...............................................
Q # 05
Selling Price = Markup + Cost
Markup = 2400 x 40/100 = Rs 960/-
Selling Price = 2400 + 960 = Rs. 3,360/-
Q # 06
Selling Price = C + (C X MUC)
3200 = C (1+MUC)
3200 = C X (1+ 0.48)
= 3200/1.48
Cost Price = Rs. 2,162
Markup = 2162 x 48/100
Markup = Rs. 1037.76/-
Q # 07
SINGLE TRADE DISCOUNT
Net Price = L (1 ΠD)
= 100 (1-.05)(1-.07)(1-.11)
= 100 (.95) (.93) (.89)
= 100 (.7863)
= 78.63
SINGLE DISCOUNT = 100 Π78.63
= 78.63%
Q # 08
Let selling price = 100
%Markup on selling price = 38%
Cost = 100-38 = 62
Thus Orignal Sale Price = (100/62) x 2,300
= Rs. 3,709.677
Rs. Markdown
%Markdown = 30%
Rs. Markdown = 3709.677 x .30 = Rs. 1,112.903
Sale price after Markdown = 3,709.677 Π1,112.903
= Rs. 2,596.774/-
Selling Price = Markup + Cost
Markup = 2400 x 40/100 = Rs 960/-
Selling Price = 2400 + 960 = Rs. 3,360/-
Q # 06
Selling Price = C + (C X MUC)
3200 = C (1+MUC)
3200 = C X (1+ 0.48)
= 3200/1.48
Cost Price = Rs. 2,162
Markup = 2162 x 48/100
Markup = Rs. 1037.76/-
Q # 07
SINGLE TRADE DISCOUNT
Net Price = L (1 ΠD)
= 100 (1-.05)(1-.07)(1-.11)
= 100 (.95) (.93) (.89)
= 100 (.7863)
= 78.63
SINGLE DISCOUNT = 100 Π78.63
= 78.63%
Q # 08
Let selling price = 100
%Markup on selling price = 38%
Cost = 100-38 = 62
Thus Orignal Sale Price = (100/62) x 2,300
= Rs. 3,709.677
Rs. Markdown
%Markdown = 30%
Rs. Markdown = 3709.677 x .30 = Rs. 1,112.903
Sale price after Markdown = 3,709.677 Π1,112.903
= Rs. 2,596.774/-
