partha earns 15% on an investment but losses 10% on another investment. If the ratio of two investments is 3:5, then the combined loss percent is?

• 0.625%
  
  Let the two investments be 300 and 500 respectively.
  Sum of the investments = 300+500 = 800
  Total earnings = 300x(115/100) + 500x(90/100) = 795
  So % loss = (800 - 795)x100/800 = 5/8 = 0.625

• total loss= 15%*3+(-10%)*5=45%-50%=5%
  total item=3+5=8

• Let investments be 300 and 500
  So total income = 0.15*300 - 0.1*50(-ve since its a loss) = 45-50 = -5 Therefore income = 800+(-5) = 795.
  Thus, Loss = (5/800)*100 = 0.625

• let us take Two investments would be 300:500(800 total investment)
  Then After 15% profit on 1st investment and 10% loss on 2nd investment
  the ratio becomes 345:450(Total 795 achieved)
  therefore loss=5
  loss%=0.625
