The reflex angle between the hands of a clock at 10 hours 25 minutes is 197 1/2 degrees. Explanation: FORMULA A = 30H - (11/2)M A is the required angle H is the position of the hour hand M is the minutes [adinserter block="7"] A = 30 x 10 - (11/2) x 25 A = 300 - 275/2 A = (600 - 275)/2 A = 325/2 A =Read more
The reflex angle between the hands of a clock at 10 hours 25 minutes is 197 1/2 degrees.
FORMULA
A = 30H – (11/2)M
- A is the required angle
- H is the position of the hour hand
- M is the minutes
A = 30 x 10 – (11/2) x 25
A = 300 – 275/2
A = (600 – 275)/2
A = 325/2
A = 162.5

The minute hand in a clock moves around 24 times in a day.
The hour hand in a clock moves around 2 times in a day i.e., it completes one rotation every 12 hours.
In 12 hours, the hour hand makes one rotation, and the minute hand makes 12 rotations. So the minute hand passes (coincides with) the hour hand 11 times in 12 hours or 22 times in 24 hours.

Height of the table is 150 cms.
Explanation:
From the given figure,
Consider the heights of Cat as C, Tortoise as D, & Table as T.
It can be observed from Figure 1 that C + T – D = 170 cms
and from Figure 2, it is clear that D + T – C = 130 cms
Consider these two statements and add them –
We will get, T + T = 170 + 130 cms
So, 2T = 300 cms
T= 150 cms.
Hence, the height of the table is 150 cms.

The clock ticks six o'clock in 26 minutes. Explanation: As per the given data, the clock has already ticked 3 o'clock. So, let's consider there are "M" minutes until it's six o'clock in that clock.

The clock ticks six o’clock in 26 minutes.
As per the given data, the clock has already ticked 3 o’clock. So, let’s consider there are “M” minutes until it’s six o’clock in that clock.
When you observe, there are 180 minutes between 3 o’clock and 6 o’clock. So, it is clear that 180 – M is the number of minutes past 3 o’clock. And also, according to the question, 50 minutes ago it was four times the minutes past 3 o’clock.
So, we need to consider 180 – 50 = 130 minutes instead of 180 minutes as it was already past 50 minutes.
Now, the required minutes is 4 times. So, it will be 4 x M.
==> 4M = 130 – M
==> 4M + M = 130
==> 5M = 130
==> M = 26

Between 3 o'clock and 4 o'clock, the needles will coincide with each other at 16 4/11 minutes past 3.

Between 3 o’clock and 4 o’clock, the needles will coincide with each other at 16 4/11 minutes past 3.
FORMULA
A = 30H – (11/2)T
- A is the given angle
- H is the initial position of the hour hand
- T is the required time
At the point of coincidence, the angle between the two needles will be ZERO degrees. So,
0 = 30 x 3 – (11/2)T
(11/2)T = 90
11T = 180
T = 180/11 = 16 4/11 minutes past 3
See lessHence, the minute hand and the hour hand will coincide at 16 4/11 minutes past 3

The face of a clock is a circle which is divided into 60 minute spaces. The minute hand of the clock ticks all the 60 minute spaces in an hour whereas the hour hand of the clock passes over 5 minute spaces. So, the minute hand is always said to gain 55 minutes over the hour hand in any clock.

The watch loses 32 8/11 minutes per day Explanation: A minute hand passes through over 55 minute spaces in an hour i.e. 60 minutes. Let's find the time taken by the minute hand to cover 60 minute spaces - 55 minute spaces = 60 min 60 minute spaces = X By cross multiplication, X = (60 x 60)/55 = 60 xRead more
The watch loses 32 8/11 minutes per day
A minute hand passes through over 55 minute spaces in an hour i.e. 60 minutes. Let’s find the time taken by the minute hand to cover 60 minute spaces –
55 minute spaces = 60 min
60 minute spaces = X
By cross multiplication, X = (60 x 60)/55 = 60 x 12/11 = 65 5/11 minutes.
As per the data given, the hands of the clock coincide every 64 minutes. This means, there are 64 minute spaces in that clock.
So, in order to get to know how many minutes are lost in that clock in 64 minutes, we need to subtract the minutes in this clock from the minutes in the normal clock ==> 65 5/11 – 64 = 16/11 minutes.
Hence, the given clock is losing 16/11 minutes every 64 minutes. In that clock, 24 hours = 24 x 60 minutes
64 minutes = 16/11 min lost
24 x 60 minutes = X
X = (16/11)×(1/64)×24×60
X = (1/11) x 360
