A.
200/3%

B.
100

C.
316/3

D.
120

• Let the CP be Rs100 and Sp be Rs.x, then the profit is x-100
  Now the SP is doubled then The new SP is 2x
  New profit is 2x-100
  Now as per the given condition; 3(x-100)=2x-100
  solving we get x=200
  Then the Profit percent =(200-100)/100
  Hence the profit percentage is 100%

• let c.p=100
  s.p is doubled so s.p=2*100=200
  gain=s.p-c.p=200-100=100
  profit%=(gain*100)/c.p=(100*100)/100=100

• s.p = rs x
  c.p= rs y
  profit =(x-y)
  if s.p doubles and profit triples
  3(x-y)= 2x-y
  3x-3y=2x-y
  x=2y
  now
  s.p=2y
  c.p = y
  profit = 2y-y
  = y
  profit %= y/y*100
  = 100%
