Question

Jyoti bhaiya table fan at 25% discount and sell it for 660 making a profit of 10% what was the market price of the fan

Answer 1

Discount =25%

Selling price (ram sell it) =₹660

Profit =10%

Cp of fan for ram =selling price - 10% of cp

660-10% of cp =cp

If he got 10% profit then selling price =100+10%
=110%

Then
110%=660
1%=660/110
1%=6

Cp=100%
Cp=100x6=600

Or u can use direct this formula
Cp=spx100/(100+profit)
Cp=660x100/(100+10)
Cp=660x100/110
Cp=6x100=60

Now at the time of buying that ram got discount of 25%

So
Mrp=cpx100/(100-discount)
Mrp=600x100/(100-25)
Mrp=600x100/75
Mrp=₹800
