Given :   A clock 's hands coincide every 65 minutes

To find : How much does a clock lose per day

Step-by-step explanation:

Hands of clock coincide 11 times in 12 hours

Hands coincide every 65 minutes

=> 65 * 11 =  in 715  minutes  Clock shows 12 hours

12 Hours has  720 minutes

Hence clock is gaining a time of  5 mins every 12 hours  

in day there are 24 hours

hence clock will gain 2 * 5  = 10 mins

10 minutes a day are gained by clock if its hands coincide every 65 minutes

Another way to interpret the  Question

in 65 minutes  hour hands movement  =  65/2  deg

in 65 minutes minute hand movement should be 65 * 6 = 360 + 30 deg
