There is a 60 minute gap between the two clocks.

These 60 minutes result of a 1 min advance in one for each hour and a 2 min loss in the other.

if we are going 2 mins back and 1 min in

We have a 3 min gap/hour

then to reach a 1 hour gap we would need to go for 2+1+2+1+2+1+2....(20 hours)

since each 3 represent an hour,

to get 60 min gap>60/3=20 hours

Take clock 1 for example, which read 12:00, in reality the time is (12:00-20 minutes)=11:40

or

Take clock 2 for example, which read 11:00, in reality the time is (11:00+20×2 minutes)=11:40

Now go back 20 hours from that;

11:40-20=00:40-9=15:40

There's ur answer 15:40 :)
