if a sales man gets successive gain of 15% and 20% then his actual gain?
ans. 38

• let c.p=100
  15% gain-> 100+15=115
  20% gain on 115= 115+ (11.5*2)=115+23=138
  so ans=138-100=38

• final gain= 15+ 20+ (15*20)/100=38

• consider the C.p=100,
  (115/100)*(120/100)*100=138
  net gain=138-100=38

• it as the formula ie x+y+xy/100
  where x is 15 and y is 20
  15+20+15*20/100
  =38

• Such questions can be solved in the following way:
  Total price = (1-0.2)*(1-0.15) = 0.8*0.85 = 0.68 = 68% of the original price
  So, total discount = 32%

• let CP=100.
  then, on 15% gain, SP will be = 100 + (15*100)/100 = 115.
  now, on 20% gain on this SP, new SP will be = 115 + (20*115)/100 = 115 + 23 = 138.
  therefore, total gain on CP = 38%.

• 15% gain
  that is,
  (85 * 80)/100 = 68
  Now,
  100-68 = 32
  so, 32 is ans.
