Question

Ram sold a laptop to Shyam at the profit of 10% . Shyam sold the same laptop to the Jadhu at the profit of 10%.if Jadhu paid ₹ 36,300for the laptop, what was the cost price of Ram ?

Answer 1

lets say initial cp of ram is x.
10% profit of x is 0.1x so the sp is 1.1x.
repeat this again for shyam, apply 10% on 1.1x it becomes 1.21x which is what Jadhu paid.
hence the below equation.

1.21x =36300 then x =30000

Answer 2

Jadhu paid ₹36,300

Find the price Shyam paid for the laptop:

Profit = 10%

Selling Price = 100 + 10 = 110%

110% = ₹36,300

1% = 36,300 ÷ 110 = ₹330

100% = 330 x 100 = ₹33,000

Find the price Ram paid for the laptop:

Profit = 10%

Selling Price = 100 + 10 = 110%

110% = ₹33,000

1% = 33000 ÷ 110 = ₹300

100% = 300 x 100 = ₹30,000

Answer: Ram paid ₹30,000 for the laptop
