After allowing two successive discounts of 10% and x% a loss of 13.6% is obtained what is the value of x, if the article was marked 20% above the cost?
a)4 b)20 c)12 d)16

• it is b)20
  assume article has value 100 rs
  as article was marked 20% above cost,it becomes 120 rs
  after allowing 1st 10% discount it becomes 120-12=108
  if we take x=20 then it becomes 108-20% of 108=108-21.6=86.4
  so 100-86.4=13.6% loss is obtained

• let the CP=100
  MP=120
  after first discount it will be 120-(10%of 120)
  =120-12
  =108
  x% x%
  108------------->(100-13.6)===>108------------->86.4
  10% of 108=10.8
  20% of 108= 2*10.8=21.6
  therefore 20

• let the price be a now
  a*9/10*x/100 =86.4/100
  by solving it x = 4%
