a fruit seller makes a profit of 20% by selling mangoes at a certain price.if he charges rs1 more for each mango,he can make a profit of 40%.find the seling price of a mango in the first case.

• cp= (1/(140-120))*100=5
  sp=5+ 5*(20/100)
  = 5 + 1
  =6

• Let initial Cost price was X.
  Then SP = X + 20% of X = 1.2X.
  If SP increased By 1 then
  1.2X + 1 = X + 40% of X
  1.2X + 1 = 1.4X
  .2X = 1
  X = Rs. 5.
  Starting SP = Rs. 5.

• let C.P. of a mango = x rs,
  therefore sp1 = x*120/100,
  sp2 = x*140/100=x*120/100+1,
  solving sp2 we get x=5,
  
  So puting x=5 in sp1 we get sp1=6 ans.

• let the cp = xrs.
  profit% is given = 20% .
  i.e sp1=(x*20)/100 + x.
  now if add sp in 1rs each(we use onl one mango) then,
  sp2=(x*20)/100 + x + 1.
  which is 40% of the cp is given .
  so ,
  cp =xrs of 40% profit = sp2.
  x + (x*40)/100 = x + (x*20)/100 + 1.
  100x + 40x = 100x + 20x + 100.
  20x = 100.
  x=5rs (cost price for each mango).
  and , 1st case sp1 = (x*20)/100 + x.
  sp1 = 6 rs.(ans)

• cp = x, sp1 = 1.2x
  sp2 = 1.2x+1
  in both cases, cp is same
  100sp1/(100+20) = 100sp2/(100+40)
  12sp2 = 14sp1
  12(1.2x +1) = 14*1.2x
  x= 12/2.4 = 5

• let cost price of a mango be c.p
  and selling rice be s.p
  
  for 20% profit we have...
  
  20 = ((s.p - c.p) / c.p) * 100
  
  for 40% profit we have
  
  40 = (((s.p+1) - c.p) / c.p) * 100
  
  solve for s.p
  s.p. = 6

• C.P. of two horses = Rs. 8000
  S.P. of one horse = Rs. 4000
  Gain = 25%
  ∴ C.P. of this horse = Rs (100/125) x 4000 = Rs.3200
  C.P. of another horse = Rs. (8000 - 3200) = Rs. 4800
  S.P. of this horse = Rs. 4000
  ∴ Loss% = (800/4800) x 100 % = 162/3%

• let cp=X
  first sp=120% of X
  second sp=140%of X
  seller increase 1 rs
  so equation will be
  140/100*X-120/100*X=1
  
  
  so X =5
  
  
  so in first case sp=120% of 5
  =6 ans
