An orange vendor makes a profit of 20% by selling oranges at certain price. If he charges Rs. 1.2 higher per orange he would gain 40%. Find the original price at which he sold an orange.
a) RS. 5.6
b) Rs. 7.2
c) Rs. 4.8
d) Rs. 8
e) None of these

• Let the CP be Rs. x per orange
  Profit = 20%
  SP = [(100+profit)/100]*cp
  SP = (120/100)*x ==> 1.2x
  Now :-
  SP =x+ Rs.1.2
  Profit = 40% ==> (140/100)*x
  Therefore, we can say
  1.40x = x+1.2 or x = Rs. 3
  Hence, Original SP = Rs 1.2x = Rs. 3.60/-

• Let the CP be Rs. x/ orange
  Profit = 20%
  SP = Rs. 1.20x
  Now, If case :-
  SP =x+ Rs.1.2
  Profit = 40%
  Therefore, we can say
  1.40x = x+1.2 or x = Rs. 3
  Hence, Original SP = Rs 1.2x = Rs. 3.60/

• 20=(sp-x)*100/x
  40=(sp+1.2-x)*100/x
  on solving this equations
  x=6
  sp = 20% of x
  therefore,
  sp=7.2

• s.p/s.p+1.2 = 120/140
  s.p/s.p+1.2 =12/14
  s.p(14) =(s.p+1.2)(12)
  14sp=12sp+14.4
  2sp=14.4
  sp=7.2

• Let the CP be Rs. x per orange
  Profit = 20%
  SP = [(100+profit)/100]*cp
  SP = (120/100)*x ==> 1.2x
  Now :-
  SP =x+ Rs.1.2
  Profit = 40% ==> (140/100)*x
  Therefore, we can say
  1.40x = x+1.2 or x = Rs. 3
  s.p at which he sold= 3*1.2+1.2= 4.8

• Let x be the C.P. of an orange.
  A/Q - the profit double itself if vendor charges Rs. 1.2 more..
  X*20% = 1.2
  X = 6
  i.e. S.P. = 6 + 20% = 7.2

• let c.p be 'x' and s.p='y'
  orange vendor makes a profit of 20% therefore gain%=20%
  
  gain%=(gain*100)/c.p where gain =s.p-c.p
  20=[(y-x)*100]/x
  
  20x=(y-x)*100
  2x=10y-10x
  12x-10y=0-------(1)
  
  
  he charges 1.2 extra per orange and he got gain 40%
  
  there s.p=y+1.2
  already c.p is assumed as x (above)
  
  again, gain%= (gain*100)/c where gain =s.p-c.p
  
  40=[(y+1.2-x)*100]/x
  
  40x=(y+1.2-x)*100
  4x=10y+12-10x
  14x-10y=12---------(2)
  solve (2) &(1)
  
  14x-10y=12
  12x-10y=0
  - + -
  ---------------------
  2x=12
  therefore x=6 [x=c.p]
  originally vendor sold price be x+1.2=7.2
