profit = s.p - c.p
let x be the no. of copies sold.
s.p = .50x
c.p = (.70x - 15000)
each copies is cost to them is for rs. 0.70x
but 15,000 has been subtracted because they have received it
as an advertisement money (consider it as donation)
hence

profit = 8000
8000 = .50x - (.70x - 15000)
x = 35000

If x copies are to be made, then
0.5x + 15000 = 0.7x+8000
0.2x = 7000
x= 7000/2= 35000

for 1 copy 0.70ps,in 15000rs hw many copies?
15000/0.70=21,428.
for 1 copy 0.50ps,in 8000rs hw many copies?
8000/0.50=16000 is the answer may b.

Copy is sold at loss =0.70-0.50=0.20
Even then a profit of 8000 is made.
Let N be no. of copies.
Therefore,
(N*0.2)+8000=15000
N*0.20=7000
N=35000
So 35000 copies sold
