16.
At what time, in minutes, between 3 o'clock and 4 o'clock, both the needles will coincide each other?
Answer: Option
Explanation:
At 3 o'clock, the minute hand is 15 min. spaces apart from the hour hand.
To be coincident, it must gain 15 min. spaces.
55 min. are gained in 60 min.
| 15 min. are gained in |  |
60 | x 15 |  min |
= | 16 | 4 | min. |
| 55 | 11 |
 The hands are coincident at 16 |
4 | min. past 3. |
| 11 |

12 to 1 = 5.
1 to 2 = 5.
2 to 3 = 5.
= 15.
=15/(11/12).
= 15 * 12/11 = 180/11,
=11 4/11 ans.
1 to 2 = 5.
2 to 3 = 5.
= 15.
=15/(11/12).
= 15 * 12/11 = 180/11,
=11 4/11 ans.

55 min is there because.
In one hour (60 min), the minute hand is 55 min ahead of the hour hand.
In one hour (60 min), the minute hand is 55 min ahead of the hour hand.

Thanks @Sai.
For giving formula for coincide (5 (H) +0) * (12/11) h =3.
For giving formula for coincide (5 (H) +0) * (12/11) h =3.

I have formula for clocks coincide.
= (5(H)+0)*(12/11) where H = 3.
= (5(H)+0)*(12/11) where H = 3.
