It takes X 2 men to do a work in 2Y days and it takes X 6 men to do the same work in Y days Quantity...........

It takes (X-2) men to do a work in 2Y days and it takes (X+6) men to do the same work in Y days.

Quantity I: X

Quantity II: Y

Quantity I > Quantity II

Quantity I ≥ Quantity II

Quantity II > Quantity I

Quantity II ≥ Quantity I

Quantity I = Quantity II or Relation cannot be established

As the time is becoming half so means number of people have doubled;

So (X+6)=2*(X-2)=>X=10
Using M1D1=M2D2 the value of Y cannot be found.

Y can take any value. So we cannot determine a unique value of Y

Hence, option 5 is the correct answer.
