Question

12) A shopkeeper gives 10%
discount on a washing machine,
hence the cost price of it is Rs.
13,500. Then find the marked
price of the television set. *​

Answer 1

Answer:Let marked price of each article was Rs. 100

After giving 10% on MP, SP of each article becomes Rs. 90

Then,

SP of 24 articles =20×90= Rs. 1800   ...[ 4 articles are given free of cost on buying 20. ]

Now, shopkeeper earns 25% profit on CP means,

CP+25%ofCP=SP

[CP+  

100

25CP

​  

]=SP

100

[100CP+25CP]

​  

=1800

125CP=180000

CP=Rs.1440

CP of one article =  

24

1440

​  

=Rs.60

Now, % MP above CP =  

100

60

40

​  

 

​  

=66.66%=66(2/3)
