Correct

cal. exact min [12AM TO 1AM]

30 =[30H-5.5M] here 30 =degree and h=0

m= 5.4545 . for calculate sec multiply 0.4545*60 = 27.27 sec.

entry time 12:05:27 and leave exact 1h20 min so

exit time =1:25:27, A=1 B=25 C=27

A+B+C = 53

The time is taken mod 12 , so 12 means 0

If you are asked to calculate the angle between the hands of the clock at 19:30( which is 7:30 pm) , you can simply calculate for 7:30 and it will be same for AM and PM ,

For 19 , we do 19 mod 12 , and 19 mod 12 is equal to 12 , similarly for 12:30, you can find the angle between the hands at 00:30 , because 12 mod 12 is equal to 0 ,
