At what time between 9.13 and 10.12 will the hands of a watch be together?
Answer: B
To be together between 9 and 10 o'clock, the minute hand must gain 45 min. space
55 min. spaces are gained in 60 min.
45 min spaces would be gained in (60/55 × 45) min. or 49 1/11 min.
The hands are together at 49 1/11 min. past 9.

At what time between 4 and 4.59 will the hands of a watch point in opposite directions?
Answer: D
At 4 o'clock, the hands of the watch are 20 min. spaces apart.
To be in opposite directions, they must be 30 min. spaces apart.
Minute hand must gain 50 min. spaces.
55 min. spaces are gained in 60 min.
50 min. spaces are gained in 60/55 x 50 = 54 (6/11) min
Required time = 54 6/11 min past 4

The angle between the minute hand and the hour hand of a clock when the time is 8.30, is
Answer: B
At 8 o’ clock, the hour hand is at 240 degrees from the vertical.
In 30 minutes,
Hour hand = 240 + 30 x (0.5) = 240 + 15 = 255 (The hour hand moves at 0.5 dpm)
Minute hand = 30 x (6) = 180 (The minute hand moves at 6 dpm)
Difference or angle between the hands = 255 - 180 = 75 degrees.
