Finding Angle between Hour and Minute Hand Video Lecture | General Intelligence and Reasoning for SSC CGL

Ans. To find the angle between the hour and minute hand at 3:45, we first calculate the angle made by the hour hand with 12 o'clock position, which is 112.5 degrees. Then we calculate the angle made by the minute hand with 12 o'clock position, which is 270 degrees. Finally, we subtract the smaller angle from the larger angle to get the angle between the hour and minute hand, which is 157.5 degrees.

Ans. To find the angle between the hour and minute hand at a given time, we follow these steps: 1. Calculate the angle made by the hour hand with 12 o'clock position by multiplying the number of hours by 30 (360 degrees divided by 12). 2. Calculate the angle made by the minute hand with 12 o'clock position by multiplying the number of minutes by 6 (360 degrees divided by 60). 3. If the hour hand has moved partially between two hour markings, calculate the additional angle by multiplying the number of minutes by 0.5 (30 degrees divided by 60). 4. Subtract the smaller angle from the larger angle. 5. If the obtained angle is larger than 180 degrees, subtract it from 360 degrees to get the smaller angle between the hour and minute hand.

Ans. To find the angle between the hour and minute hand at 6:30, we first calculate the angle made by the hour hand with 12 o'clock position, which is 195 degrees. Then we calculate the angle made by the minute hand with 12 o'clock position, which is 180 degrees. Finally, we subtract the smaller angle from the larger angle to get the angle between the hour and minute hand, which is 15 degrees.

Ans. To determine if the hour and minute hand are pointing in opposite directions, we can compare their angles. If the angle between the hour and minute hand is greater than 180 degrees, then they are pointing in opposite directions. If the angle is less than 180 degrees, they are pointing in the same direction.

Ans. The hour and minute hand form a straight line when they are pointing in the same direction, which happens twice a day. The first occurrence is at 12:00, where both hands are pointing straight up. The second occurrence is at 6:00, where both hands are pointing straight down.
