Answer 1

4) The profit is 10 %

Please refer the above attachments

5)A shopkeeper bought a chair in Rs.375.

So, C.P=Rs.375

And he sold a chair in Rs.400

So, S.P=Rs.400

 We know that

Gain(%)=C.PS.P−C.P×100

Gain(%)=375400−375×100

Gain(%)=37525×100

Gain(%)=6.667%

6) Cost price of article=Rs. 1960

Shopkeeper's profit=10%

⟹ Profit =10%×1960=196

∵  Selling price = Profit + Cost price

∴  Selling price of the article =Rs. 1960+Rs. 196=Rs. 2156
