The time at which the hands of the clock will be in 180 degrees between 9 and 10 'o'clock is 180/11 min past 9. Explanation: Formula to find the time of a clock when an angle and hour is mentioned is A = [30H - (11/2) x minutes] Here, A = Given Angle H = Initial position of the hour hand [adinserterRead more
The time at which the hands of the clock will be in 180 degrees between 9 and 10 ‘o’clock is 180/11 min past 9.
Formula to find the time of a clock when an angle and hour is mentioned is A = [30H – (11/2) x minutes]
Here,
Now, using the formula, we get –
==> 180 = 30 x 9 – 11/2 m
==> 180 + 11/2 m = 270
==> 11/2 m = 270 – 180 = 90
==> 11m = 90 x 2
==> m = 180/11
See lessHence, at 180/11 minutes past 9, the hands of a clock will be in 180 degrees stretch between 9 ‘o clock and 10 ‘o clock.
75 degrees is the angle between the minute hand and the hour hand of a clock when the time is 8:30. 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 8 - (11/2) x 30 A = 240 - 165 A = 75 Hence, the twoRead more
75 degrees is the angle between the minute hand and the hour hand of a clock when the time is 8:30.
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 8 – (11/2) x 30
A = 240 – 165
A = 75
Hence, the two hands of a clock will be inclined at an angle of 75 degrees when the time is 8 hours 30 minutes.

Explanation: When you keenly observe the given figure (Clockwise) from the top clock, [adinserter block="7"] The minute hand is moving clockwise 15 minutes in each figure The hour hand is moving anti-clockwise 2 hours in each figure So, as the secRead more
The hour hand on the bottom clock should point to 8.
When you keenly observe the given figure (Clockwise) from the top clock,
See lessSo, as the second figure shows the hour hand on 10, the next clock figure should have its hour hand pointing towards 8.
The puzzle can be solved as below, 2 x 1 + 1 = 3 3 x 2 + 2 = 8 4 x 3 + 3 = 15 5 x 4 + 4 = 24 In the same way, 7 x 6 + 6 = 48. Hence, the answer is 48
The puzzle can be solved as below,
2 x 1 + 1 = 3
3 x 2 + 2 = 8
4 x 3 + 3 = 15
5 x 4 + 4 = 24
In the same way, 7 x 6 + 6 = 48.
Hence, the answer is 48
See lessThe 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
See lessThe Reflex Angle of 162.5 is 360 – 162.5 = 197.5 degrees or 197 1/2 degrees
The minute hand in a clock moves around 24 times in a day. [adinserter block="7"] 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 (cRead more
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.
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
See lessHence, 26 minutes are left until the clock ticks six o’clock
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
In the given figure, there are 45 squares. Explanation: Total number of columns in Big Square = 4 Total number of rows in Big Square = 4 So, rows = columns Formula = 12+22+32+42 = 1 + 4 + 9 + 16 = 30 Now, number of small squares = 3 each with 5 squares = 3x5 = 15 Hence, total number of suares = 30 +Read more
In the given figure, there are 45 squares.
Explanation:
Total number of columns in Big Square = 4
Total number of rows in Big Square = 4
So, rows = columns
Formula = 12+22+32+42
= 1 + 4 + 9 + 16
= 30
Now, number of small squares = 3 each with 5 squares = 3×5 = 15
Hence, total number of suares = 30 + 15 = 45
