Raj earns 25% on an investment but losses 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?

3.125% gain
6.25% loss
13.125% loss
13.25% gain

• ratio=3:5
  profit=25% loss=10%
  total profit/loss=(3*25 - 5*10)/3+5
  =25/8=3.125

• 3.125%
  300*25/100=75 gain, 500*10/100=50 loss
  75-50=25 gain on (300+500)=800,so percentage of gain=25*100/800=3.125%..done (y)

• {(25/100)*3x-(10/100)*5x}/8x=3.125

• this problem can also done by using mixture and alligation
  25 -10
  x
  3 5
  
  => -10-x / x-25 =3:5
  => 5(-10-x) =3(x-25)
  there fore by solving this equation we get x=3.125% gain
