Question

P sells an article to Q at 10%profit. Q sells it to R at 25% profit. If R pays ₹250 for it, what did P pay for it?
( step by step)​

Answer 1

Let the C.P of the object be X rupees.

P sells it to Q at 10 percent profit.

So Q bought it for X + X x 10/100

Q sells it to R at 25 percent profit and R pays about 250 rupees for the object.

Q's selling price = (X + X x 10/100) + (X x 25/100)

Equate the selling price with R's amount paid.

X + X/10 + X/4 = 250

20X + 2X + 5X = 250 x 20

27X = 5000

X = 5000/27 = 185.18

Hence P bought it for Rs. 185.18

Answer 2

Answer:

price Q payed =a

a x 125 / 100 = 250

a = 200

price payed by P = y

y x 110 / 100 = 200

y = 200 x 100 / 110

y = approx 181.1 rupees
