A tradesman marks his good 30% above the cost price.if he allows a dicount of 6 1/4%. then his gain percent is:

• let cp =100
  mp=130
  sp=(1-25/400)130=121.875
  p%=21.875

• its quite simple
  assume its cp is 100
  after marking 30% it becomes 130 rs.
  discount provided is 6 1/4 % =25/4%
  25/4 % of 130 rs is 8.125 rs.
  hence sp becomes 121.875 rs
  hence profit=21.875 rs which is 21.875 % on 100 rs

• let c.p be x then s.p will be 13x/10
  discount= 25% of s.p= 13x/160
  now the reduced s.p = 39x/32
  the gain= (39x/32-x)= 7x/32
  gain %= 21.875 %

• let cp=100
  mp=130
  sp=130-(25/400*130)=975/8
  profit=975/8-100
  %profit=profit/100*100
  21.8
