Question

A shopkeeper gives 10% discount on printed price of an articles. Then he applies 5% GST on
Reduced price . How much amount is payable by custmer. Take printed price as input.
​

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)%
