Answer: Option
Explanation:
| Angle traced by hour hand in | 13 | hrs = |  |
360 | x | 13 |  |
° | = 130°. |
| 3 | 12 | 3 |
| Angle traced by min. hand in 20 min. = | |
360 | x 20 | |

Hi All,
We can write 4 hrs. 20 mins. as 13/3 hrs.
13/3 = 4 and (1/3)hrs
= 4.20 ( Here 1 hour = 60 mins, 1/3 of 60 is equal to 20).
Hope you understand guys. Have a nice day!

angle=(11/2)*min-30*hrs
apply this formula you can get the answer ......

we can convert it in hours as:
20min.=1/3hours
so total hours as 4+1/3=13/3
20min.=1/3hours
so total hours as 4+1/3=13/3

By common sense it is clear that in 20 minutes the minute hand will move 20*6=120degree and the hour hand will move20*(1/2)=10degree.
Clearly min hand will be at 20 and hour hand will be 10degree apart.
Clearly min hand will be at 20 and hour hand will be 10degree apart.

Apply the formula suggested by Reddilavan..
ie: Angle = 30Hr-(11/2)Min
ie: Angle = 30Hr-(11/2)Min

Hi girls ! we can write 4.20 also as 13/3, we covert 20 min into hrs 20/60=1/3 and we add with4 hrs 4+1/3=13/3.
Have a nice day.
Have a nice day.

Direct formula:
|11M-60H|/2
where M=minute, H=hour hands.
|11M-60H|/2
where M=minute, H=hour hands.
