Two electronic musical instruments were purchased for Rs. 8000. The first was sold at a profit of 40% and the second at a loss of 40%. If the sale
price was the same in both the cases, what was the cost price of the electronic musical instruments?

• let cost prices be x and 8000-x
  s.p1=s.p2
  (140/100)*x=(60/100)*(8000-x)
  x=2400
  cost prices are 2400,5600

• c.p=8000
  s.p1=(100+40)/100*(8000)=11200
  s.p2=(100-40)/100*(8000)=4800
  sp of two items =11200,4800
  sp of one item=5600,2400

• let c.p. be x and 8000-x
  s.p1=x+(x*40)/100===140x/100
  s.p2=(8000-x)-(8000-x)*40/100===(480000-60x)/100
  sp1=sp2
  140x/100=(480000-60x)/100
  x=2400
  8000-x=5600
  ans is 2400,5600

• let two cp be x1,x2
  so 140*x1/100=60*x2/100
  x1/x2=3/7
  x1=8000*3/10=2400
  x2=8000*7/10=5600

• 4000×40/100=1600.profit 4000+1600=5600
  4000×40/100=1600.loss 4000-1600=2400

• 100------>140
  100------->60
  but selling price is same so
  300---->420
  700----->420
  _____________
  1000(cp of both) so 8000/1000*300=2400
