Two articles were sold at Rs. 480 each. On one, he gains 20% and on the other, he loses 12%. How much does he gain or lose in the whole transaction?

• for the 1st article,cost price
  =(100*480)/(100+20)=400
  for the 2nd article,cost price
  =(100*480)/(100-12)=545.45
  total CP=400+545.45=945.45
  total SP=480+480=960
  so profit=960-945.45=14.55
  %gain=(14.55*100)/945.45=1.54%

• sorry.. did a mistke..
  1.2x=480; x=400
  .88y=480; y=545
  totl cst prc=400+545.45=945.45
  salng prc=2*480=960
  prft=960-945.45=14.55
  %=14.55/945.45=.0154=1.54% (ans)

• Lets take calculation on 100
  if 120 is the sp then 100 is the cp
  1 sp then cp is 100/120
  480 sp 100/120*480=400
  similarly
  if 88 is the sp then 100 is the cp
  1 100/88
  480 is the sp then 100/88*480=545.45=545(let)
  total 545+400=945
  480+480=960
  if we sell at 945 then 15 is the profit
  1 15/945
  100 15/945*100=1.5 gain(approx)

• Ans:- profit of 1.5%
  we can solve this by using harmonic mean formulae.
  2ab/a+b -100 = 2*120*88/120+88 -100 = 1.5%.

• there is a formula if u have two difffnt artical are sold at the same s.p and having g/l of x% on the 1st and g/l of y% on 2nd then g/l will be
  
  100(x+y) + 2x.y/(100 + x) + (100 + y)
  now,
  100(20 + 12) + 2.20*12/(100+20) + (100+12)
  after solving we get 408/29 = 14.06
  gain will be 14.06

• 100+20/100=1.2
  so, 1.2x=480; x=400
  .8y=480; y=600
  total cst price=(400+600)=1000
  selling price=480*2=960
  loss=1000-960=40
  %=40/1000=.04 * 100=4prcnt

• 480=(120/100)*x
  x=400
  480=(88/100)*y
  y=545.45
  x+y=400+545.45=945.45=total cost price
  Profit=960-945.15=14.85
  14.85/945)*100=1.57%=profit percentage
