Here, I think there will be gain in time. Not a loss in time.

Use the formula.
Clock gain or loss:
720/(11-M)*(24*60)/M.
Clock gain or loss:
720/(11-M)*(24*60)/M.

As per the formula, it is;
((720/11) -64) * ( (60*24) /64).
((720/11) -64) * ( (60*24) /64).

How could you all get 720/11 - 64 = 16/11? Please explain.
