If Monday is 1st January 2018, what day is 25th January 2018?
a) Monday
b) Tuesday
c) Wednesday
d) Thursday
Answer:
d) Thursday
Explanation:To find out what day of the week January 25th, 2018 falls on, we can count the number of days between January 1st and January 25th.January has 31 days, so January 25th is 24 days after January 1st.

Since 24 is divisible by 7 (24 ÷ 7 = 3 remainder 3), it means the day of the week advances by 3 days.

So, if Monday is January 1st, then Tuesday is January 2nd, Wednesday is January 3rd, and Thursday is January 4th.

Therefore, January 25th, 2018 is a Thursday.

If a clock shows 2:30, what is the angle between the hour hand and the minute hand?
a) 45°
b) 105°
c) 90°
d) 120°
Answer: b) 105°
Explanation:
To find the angle between the hour hand and the minute hand of a clock at 2:30, we can use the following formula:

Angle = |(30*H – (11/2)*M)|

Where:

H is the current hour (in 24-hour format)

M is the current minute

For 2:30, H = 2 and M = 30.

So, the angle = |(30*2 – (11/2)*30)| = |(60 – 165)| = 105 degrees.

Therefore, the angle between the hour hand and the minute hand of the clock at 2:30 is 105 degrees

If it is currently 3:45 PM, what will be the angle between the hour hand and the minute hand of the clock?
a) 90 degrees
b) 187.5 degrees.
c) 120 degrees
d) 135 degrees

Answer: b) 187.5 degrees.

Explanation:
To find the angle between the hour hand and the minute hand at 3:45 PM:

The hour hand will be slightly past 3 but not yet at 4, so it will be closer to 3.
The minute hand will be at 9 (since 45 minutes is three-quarters of an hour).
The angle formed between the hour hand and the 12 o’clock position is (3 * 30) + (45/2) = 97.5 degrees.
The angle formed between the minute hand and the 12 o’clock position is 45 * 6 = 270 degrees.
The difference between these two angles gives the angle between the hour hand and the minute hand: 270 – 97.5 = 172.5 degrees.
However, since we want the smaller angle between them, we subtract this from 360 degrees: 360 – 172.5 = 187.5 degrees.
If a clock gains 5 minutes every hour, how many minutes will it gain in a day?
a) 120 minutes
b) 240 minutes
c) 300 minutes
d) 360 minutes

Answer: c) 300 minutes

Explanation:

The clock gains 5 minutes every hour, which means it gains 60 minutes every 12 hours.
Therefore, in a 24-hour period, it will gain 60 * 2 = 120 minutes.
So, in a day, it will gain 120 + 120 = 240 minutes.
However, it starts at midnight and finishes at midnight, so it gains an extra 60 minutes, making it a total of 240 + 60 = 300 minutes in a day.
These questions test the understanding of angles and time relationships on a clock.
