Reshma sells an article to Rekha at 37.5% profit, Rekha sells it to Madhu at 9 1/11% profit. Again Madhu sells it to Mitu at 25% loss. If Mitu pays Rs. 342 for the article, then what is the cost price of the article to Reshma?
266.50 rs.
Incorrect Answer384.75 rs.
Incorrect AnswerExplanation:
Now reshma suppose buys it for x and she sells it at a profit of 37.5% , to someone who sells it at a profit of 100/11% , to someone who sells it at a loss of 25% i.e for 342 rs.
Now, calculation hack- to caluculate x% profit on some value , the formula is value(1+x/100) and similarly for loss, it's value(1-x/100).
so to calculate 37.5% profit on x , formula is x(1+37.5/100)
now according to the question, x(1+37.5/100)(1+100/1100)(1-25/100)
x(1+3/8)(1+1/11)(1-1/4)=342
x(11x12x3/8x11x4) = 342
x = 304
