Explanation:

It is given that
From I – We get the value of x from first statement so on putting the value of x in the above equation we obtain value of y.
So, we can find the value of required time from statement I alone.
From II
On putting the value of x/y in the equation we obtain value of x and y.
So from statement II alone we can find the value of the required time.
So, from each statement individually we can find the value of required time.
