If the selling price is doubled,the profit triples.wht is is profit percent?
A.66.66
B.100
C.105.33
D.120

• Ans :100%
  let the cp be y , sp be x and profit be p
  hence by the condition given
  x-y = p ......(1)
  2x - y = 3p ......(2)
  solving this y = p
  profit % is (profit/cp)*100
  (p/p)*100 = 100%

• let c.p =100 and profit = x%,
  So, sp=100+(100+x).
  therefore,
  2*(100+100+x)=3*(100+x),
  So, x = 100 Ans.

• 100%
  let cost price of item is x and selling prince of an item is y then profit= y-x
  by given condition
  3(y-x)=2y-x =>
  y=2x
  by eqn 1st
  profit=2x-x=>x
  now profit %=(profit/cost price)*100
  profit=(x/x)*100
  =100%

• ans is 100 %

• Ans :100%
  suppose the cp is c
  sp is s
  profit is p
  so,
  s-c = p ......(1)
  2s - c = 3p ......(2)
  from both eqtn we get
  c=p
  so,profit %=(p/p)*100=100%
  profit % is (profit/cp)*100
  (p/p)*100 = 100%

• eq 1 x=x+y
  eq 2 2x=2x+3y
  eq2-eq1
  x=x+2y
  % cal
  3y*%/100=2y %=2y*100/3y=66.66%

• How plz explain

• if SP doubled the profit triples.
  so let SP= 100;the if doubled then 200;
  it results in three times of profit. so comparing 100 and 200 we can get
  
  150 as three times profit.
  so igues 50%

• let assume,
  cp sp
  25 50 so,profit=25 now
  100 so profit=75(25*3)
  original profit%=(profit/cp)*100=25/25*(100)=100%

• ans is b)
  in such type of ques
  just form the eqn & solve.

• let x be selling price and y be the cost price.
  profit=x-y
  now ,selling price=2x then
  profit=2x-y
  2x-y=3(x-y)
  2y=x
  y=x/2.
  profit=x-y
  x-x/2=x/2
  profit%=x/2/y*100=100%
  x-x/2=x/2
