Question

P sells an item to Q at a loss of 10%.
Q sells the item to R at a loss of 10% again.
R sells the item to S at a loss of 10% again.
Finally, S sells the item back to P at the same price at which P had originally bought the item.
What was S’s percentage of profit?

Round off your answer to two decimal places.

%

Answer 1

Answer:

37.2%

Step-by-step explanation:

let p bought price is x

now p sells to q at 10% loss so Q bought price is .90*x

similarly R bought price is .9*.9.x

and S bought price is .9*.9.*.9*x= .729x

now s sells to P at original price, that is x

so, S profits = (x/.729x) - 1
