10.
At 3:40, the hour hand and the minute hand of a clock form an angle of:
Answer: Option
Explanation:
Angle traced by hour hand in 12 hrs. = 360°.
| Angle traced by it in | 11 | hrs = |  |
360 | x | 11 |  |
° | = 110°. |
| 3 | 12 | 3 |
Angle traced by minute hand in 60 min. = 360°.
| Angle traced by it in 40 min. = | |
360 | x 40 | |
° | = 240°. |
| 60 |
Required angle (240 - 110)° = 130°.

Simple total min 3*60=180+40
220/60
22/6
11/3
This for hrs. so
360/12*11/3
30*11/3
= 110 ok (1)
now
for min.
360/60*40
60*40
= 240 (2)
now
(2-1)
240-110
ans. 130
220/60
22/6
11/3
This for hrs. so
360/12*11/3
30*11/3
= 110 ok (1)
now
for min.
360/60*40
60*40
= 240 (2)
now
(2-1)
240-110
ans. 130

First consider for hours hand.
1hr of hand movement = 30 degrees.
Next for min hand.
5 min of min hand = 30 degrees.
Hence for angle between them subtract the total angle made by them.

Guys got it.
If time less than 30 min use 30h - 11.5m = theta ex. for 4.10,4.15.
If time is cross 30 min use 11.5m - 30h = theta ex-for 3.40,6.40'.

I think this is the best site to prepare for any aptitude test.I will tell my friends abount this site who are unknown to this site.Because i was also unknown to this site upto this time.

While considering 3.40 we take 40 mins = 40/60 = 2/3.
So 3*2/3 = 11/3.
So 3*2/3 = 11/3.

The Angle between hour and minute hand is |(X*30) - ((Y*11)/2)|.

Always remember 1 minute = 4 degree. So what, consider time between hour hand and minute is 32.5minutes.
32.5minute*4 = 130 degree using this tip.
32.5minute*4 = 130 degree using this tip.

Formula: (+)(-)A = 30(H)-5.5(min).
= 30*3-5.5*40.
= 90-220.
= 130 degree answer.
= 30*3-5.5*40.
= 90-220.
= 130 degree answer.

I don't understand Angle traced by it in 11 hrs = 360x11° = 110°.
