• if invest ment ratio a:b:c then time period ratio t1:t2:t3 then profit ratio
  a*t1:b*t2:c*t3.. in the problem we have profit ratio 5:7:8 and time ratio 14 8 7 then investment ratio 5/14:7/8:8/7 = 20:49:64

• We know profit = investment * duration, so investment = profit / duration,
  Thus investment ratio are: 5/14:7/8:8/7
  
  LCM of 14,8,7 is 56 so
  
  Ratio is : 5*(56/14): 7*(56/8): 8*(56/7) = 20:49:64 ---> option b

• 5/14:7/8:8/7... Take out the lcm of 14,8,7 and multiply them with each fraction... (5/14)*56=20.. (7/8)*56=49.. this way its coming 20:49:64..
