A shopkeeper buys an article at ` 12000 and spends 10% of cost price as a transport. He marked price 20% above the price at which he buy and sells at mark marked price, find his profit percent.

If cost price of 11 pens is same as marked price of 9 pens. What is the profit percentage if it is same as the discount percentage offered?

correct ans:10%

solution please

Let the cost price of 1 pen be Rs 1.

CP of 11 pens = MP of 9 pens = Rs. 11

CP of 9 pens = Rs 9.

if profit is p% then ,

9 x ( 100 + p)/100 = 11 x ( 100 - p)/

Solving this we get p = 10.

Vinayak bought a ticket for the grand finale of the ‘Bull fighting’ challenge in Valencia, Spain. Unfortunately, he had to change his plans and decided to sell his ticket. He expected a lot of demand for the ticket but had to sell it for 1/2 of what he had initially quoted. This reduced his profits by 60%. His profit margin, in %, must have been

25

75

66.66

Let the price of the the ticket be X.

Quoted price : 2Y

Profit on quoted price : 2Y - X

Profit on 1/2 of quoted price : Y - X

40% of ( 2Y - X) = Y - X.

X/Y = 1/3

Profit Margin : 100 x ( 3-1)/2 = 66.66%

Sir is it wrong?

Roma sells 60 identical toys at a discount of 40% on printed price. Then she makes 20%profit. Ten of these toys are destroyesd. While selling tje rest , how much discount should be given on the printed price so that she can make the same amount on profit?

A 30

B 23

C 24

D 28

Let mp of 60 articles be 60 RS.

Discounted price = 60*(100-40)/100 =36rs

On selling at 36 RS he gains 20% so we have to maintain same price

Now 10 articles are destroyed so mp of 50 articles is 50 RS.

And we have to sell at 36 RS so discount = 14 RS

% discount = (14/50)*100 = 28%

Hence option D

If an article is sold for rs. X then there is a loss of 15%. And if the article is sold for rs. Y then there is a profit of 15%. What is the ratio of y-x/y+x ?

assume the cost of article = C

15% loss = .85c =x

15% profit = 1.15c= y

now

(y-x)/(y+x) = (1.15-0.85)/(0.85+1.15) = 0.3/2 = 3/20
