Q:

At 3.40, the hour hand and the minute hand of a clock form an angle of:

A) 120 degrees B) 125 degrees
C) 130 degrees D) 135 degrees
 
Answer & Explanation Answer: C) 130 degrees

Explanation:

Angle traced by hour hand in 12 hrs. = 360º.

 

Angle traced by it in  11/3 hrs=  36012*113°=110°

 

Angle traced by minute hand in 60 min. = 360º.

 

Angle traced by it in 40 min. =(360/60*40)°=240°

 

  Required angle (240 - 110)º = 130º.

A) 40 B) 44
C) 60 D) 56
 
Answer & Explanation Answer: A) 40

Explanation:

The given puzzle follows a logic that,

2 + 10 = 24 => 2 + 10 = 12 x 2 = 24

3 + 6 = 27 => 3 + 6 = 9 x 3 = 27

7 + 2 = 63 = 7 + 2 = 9 x 7 = 63

 

Similarly, 5 + 3 = 40 => 5 + 3 = 8 x 5 = 40.
