DETAILED SOLUTION   x, y or z cannot be greater than 24   Also x + y + z cannot be greater than 24   Given x hrs + z hrs = y hrs   Also y min + x min = z min   The only value of x that will satisfy the above 2 equations is 0.   Hence, from among the choices given, the time could be 00:02 hrs   00:02 hrsORRE00:02 hrsT ANSWER 00:02 hrs.
