Q. If a certain date is 45 days after February 15, how many days will it be in April?
A.
15
B.
16
C.
17
D.
18
Solution
February has 28 days in a non-leap year. From February 15 to February 28 is 13 days. 45 - 13 = 32 days left. March has 31 days, so 32 - 31 = 1 day into April. Thus, it will be April 1.
Q. If a cistern is filled by two pipes A and B in 12 hours and 15 hours respectively, how long will it take to fill the cistern if both pipes are opened together?
A.
6 hours
B.
7.2 hours
C.
8 hours
D.
9 hours
Solution
The combined rate is 1/12 + 1/15 = 5/60 + 4/60 = 9/60 = 3/20. Therefore, it will take 20/3 hours or 6.67 hours.

Q. If a clock shows 10:10, what is the angle between the hour and minute hand?
A.
35 degrees
B.
50 degrees
C.
60 degrees
D.
75 degrees
Solution
At 10:10, the hour hand is at 85 degrees (10 hours * 30 degrees + 10 minutes * 0.5 degrees) and the minute hand is at 60 degrees (10 minutes * 6 degrees). The angle between them is |85 - 60| = 25 degrees.
Q. If a clock shows 12:45, what is the angle between the hour and minute hands?
A.
135 degrees
B.
150 degrees
C.
165 degrees
D.
180 degrees
Solution
At 12:45, the hour hand is at 337.5 degrees (12 * 30 + 45 * 0.5) and the minute hand is at 270 degrees (45 * 6). The angle between them is |337.5 - 270| = 67.5 degrees.
Q. If a clock shows 3:15, what is the angle between the hour and the minute hand?
A.
7.5 degrees
B.
22.5 degrees
C.
45 degrees
D.
52.5 degrees
Solution
At 3:15, the hour hand is at 97.5 degrees (3 hours * 30 + 15 minutes * 0.5) and the minute hand is at 90 degrees (15 minutes * 6). The angle between them is |97.5 - 90| = 7.5 degrees.
