The percentage increase in the number of pens sold by a trader from Tuesday to Wednesday is same as the percentage decrease in the number of pens sold from Monday to Tuesday. On Wednesday the trader sold 16 pens more than those he sold on Tuesday. If the percentage decrease in sales from Monday to Tuesday is 20%, how many pens did he sell on Tuesday?
(1) 20 (2) 96 (3) 100 (4) 80

• Let number of pens sold on tuesday be x
  given that the percentage increase in the number of pens sold by a trader from Tuesday to Wednesday is same as the percentage decrease in the number of pens sold from Monday to Tuesday
  so
  percentage increase in sales of pen from tuesday to wednesday=percentage decrease in sales from monday to tuesday=20%
  then on wednesday trader sold 16 more pens than those sold on tuesday so
  number of pens sold on wednesday=x+16
  and this is 20% more than number of pens sold on tuesday so
  [1+(20/100)]*x=x+16
  6x/5=x+16
  x=80
  so number of pens sold on tuesday =x=80

• pen sold on tuesday = x
  pen sold on wednesday = x + x/5 (20 % more atq)
  
  ATQ
  x+x/5-x=16
  therefore x =80

• let the number of pens sold on tuesday is x
  now M T W
  -20% +16 (pens)
  hence , 20% of the x= x/5
  x-x/5=4x/5
  as by the question ,,
  4x/5 + 16=x
  
  //because,, 16 more pens sold on the wednesday (ie W)
  
  solving above we get x=80 (ans).

• t-w/t=m-t/w
  t-w/t=1/5 and w= 16+t so put the value of w in equation we got.
  t=80 ans

• atq
  %increase=%decrease
  use
  a+b+ab/100
  20-20-400/100

• Lets the number of pen is sold on monday is x.Therefore the number of pen is sold on tuesday is 80x/100 as the % decrease in the number of pens sold from monday to tuesday.
  Now the % increase in the number of pens sold from tuesday to wednesday is 20%.
  The sold on wednesday is 80x/100*120/100...
  Therefore,
  80x/100*120/100-80x/100=16
  By calculating x=100.(pen sold on Monday)
  Pens sold on Tuesday is 80..

• decrease in sale=increase in sale i.e 20%
  Let he sold 3 pens on tuesday then he sold 16+x pens on wednesday i.e 16 more pend
  20% of x= 16
  on solving x=80
