Answer 2

Answer:

.let the price of item= X

.number of item buy for rupees 600 =600 /

.keeping 10 items for himself he sold remaining .

items sold=600/x-10=(600-10x)/

x

a profit of rupees 5 per item

selling price=Rs(x+5)

from the amount received in this deal could buy more 15 items

for given we have

(x-5) (600-10x) =x(600+15)x

5(x+5)(120-2x) =5x(120+3x)

(x+5)(120-2x) =x(120+3x)

upon solving we get

-5^2-10x+60=0

x^2+2x-120=0

(x+12)(x-10) =0

therefore the original price of each item is Rs 10

here is your answer
