partha earns 15%on an investment but losses 10% on another investment. if the ratio of 2 investment is 3:5 then the combined loss percent is?

• 5/8%
  cp_1 = 100 x 3 cp_2 = 100 x 5
  sp_1 = 115 x 3 sp_2 =90 x 5
  total cp = 800
  total sp = 795
  loss = 5
  loss % =5/8%

• 0.625%
  
  Let the two investments be 300 and 500, total=800
  Earnings=300x(115/100) + 500x(90/100) = 795
  So % loss = (800-795)x100/800 = 5/8 = 0.625
