Raj earns 25% on an investement but Loses 10% on another investment If the ratio of the two investment is 3:5.
what is the gain or loss on the two investment taken together’

optiosn are
6.25% loss/13.125% gain/13.125% loss/3.125% gain

• Given 3 : 5
  Let suppose 300 and 500
  25% gain on 300 = 375
  10% loss on 500 = 450
  total investment 300+500= 800
  total income 375+450=825
  difference is 25,
  So (25/800)*100 = 3.125%gain

• use aligation rule
  
  25 -10
  m
  
  3 : 5
  find using 25-m/5=m+10/3
  if m is +ve then it is profit else loss

• Answer :- 3.125% gain
  
  explain :-
  
  investment ration = 3:5 :: investment A(25% profit) : investment B (10% loss)
  
  for better understanding we can say that
  
  investment A = 3 / 8;
  investment B = 5 / 8 ;
  
  let us considered investment amount is 800 (800 cause 800 easily divide by 8)
  
  800 * 3/8 = 300 Investment in A
  
  800 * (8-3)/8 == 800 * 5/8 = 500 Investment In B
  
  total investment Amount is 500 + 300 = 800
  
  300 * 5/4 (25% profit) = 375 Return (Profit)
  
  500 ka 10% Loss = 500-50 = 450 Returns (Loss)
  
  total Returns = 375 + 450 = 825
  
  Total Investment = 800
  Total Returns = 825 (Obvious it shows gain)
  
  gain % = 825 - 800 / 800 = 25/800 = 3.125% gain
