How much does a watch lose per day, if its hands coincide every 64 minutes?
Answer: Option
Explanation:
55 min. spaces are covered in 60 min.
| 60 min. spaces are covered in |  |
60 | x 60 |  min. |
= 65 | 5 | min. |
| 55 | 11 |
| Loss in 64 min. = | |
65 | 5 | - 64 | |
= | 16 | min. |
| 11 | 11 |
| Loss in 24 hrs = | |
16 | x | 1 | x 24 x 60 | min. |
= | 32 | 8 | min. |
| 11 | 64 | 11 |

How can coincide 24 times in a day, any one can explain? I think it may coincide 23 times in a day, but only meet 24 times in a day.

The hands coincide 22 times a day soo instead of 24.
22 should be used as ( (720/11) -64) *24*60. The answer would be 32 mins.

This some's difficulty is bit high, that's why here we have to consider relative speeds of hands of clock. Not separate got it?

I think question should be "How much does a watch gain per day". Because lose means it loses 16/11 min from 65 (5/11).

I guess it is the wrong question because when hands coincide after 64 min I, e < 64 5/11 then clock will gain.

I am not able to understand how 55 min. Spaces are gained by minute hand in 60 min period. Can anybody explain?

Hello @Konxie,
Why to find loss per minute? Can't we just multiply with 24?
Like, 1.45* 24...
Please tell me.

But @Abhilash can you please elaborate how the step 64*55/60 came?

Use this you will get any problem solved from clock M * 6° ~ (h + m/60) * 30°= Angle.
