30 min past 2 pm​

Answer 1

Step-by-step explanation:

For 24 hrs i.e. 24x60= 1440min, there is a gain of 10 mins.

So the ratio of real time to the time of the clock is 1440:1450 = 144:145

Here, Time elapsed in the clock is = 29 hr i.e. 29x60 = 1740

So, the real time (a) can be found by

144:145::a:1740

a= (144x1740)/145 = 1728

So the real time would be 2:48 pm
