raj earns 25 on an investment but loses 10 on another investment.if the ratio of the two investment is 3:5.what is the gain or loss on two investments taken together?

• d qstn shd b 25% and 10%
  
  taking the 2 investments to be 3x and 5x
  total income of raj = (3x)*1.25+(5x)*0.9 = 8.25
  therefore gain%=0.25/8*100=3.125%

• let 2 investment cp1=3x , c2=5x
  now, profit 25%=3x/4 ,sp1=3x+3x/4=15x/4
  similarly 10% loss=x/2, sp2=5x-x/2=9x/2
  total gain=sp-cp=(9x/2+15x/4)-(8x)=x/4
  hence gain %= (x/4)/8x *100 =3.125%.

• gain=25% and loss=10%
  two investments are 3:5
  total incom=3*125/100+5*90/100=8.25
  gain%=0.25/8.25=0.3030*100=3.03
  3.03%

• gain=25% loss=10%
  two investment=3:5 total=8
  gain
  first investment =3/8*25=9.3
  second investment = 5/8*25=15.5
  add both investment values=9.3+15.5=25(app)
  therefore 25/8=3.124 gain

• let the investment be 160
  160 divided into ratio of 3:5 as 60:100
  25% profit on 60=85
  10% loss on 100=90
  gain%=(5/160)*100=3.125%
