Q. Two guys work at some speed...After some time one guy realises he has done only half of the other guy completed which is equal to half of what is left So how much faster than the other is this guy supposed to do to finish with the first.

• if x is the part of task this is completed then,
  Ist has donework=(1-x)/4 & 2nd has done work =(1-x)/2
  so 2nd will have to increase his speed by 2 times.

• speed should be 3/2 of faster guy
  
  x/4
  x/2
  left
  3x/4
  x/2
  t1=t2
  3x/4 / x/2= y / z
  3/2 = y/z
