1.  At what time between 9 and 10 o'clock will the hands of a watch be together?

A. 45 min. past 9
B. 50 min. past 9
C. 49(1/11) min. past 9
D. 48(2/11) min. past 9

Answer: Option C

Explanation:

To be together between 9 and 10 o'clock, the minute hand has to gain 45 min. spaces.

55 min. spaces gained in 60 min.

45 min. spaces are gained in:

60 x 45 min or 49 1 min.
55 11

∴ The hands are together at 49 1 min. past 9.
