Questions Related to time

What will be the TIME parameter value , if you want it to run the job within 7min 30 sec?

  1. TIME(07,30)

  2. TIME(00,07,30)

  3. TIME(07:30)

  4. TIME(30:7)


Correct Option: A

AI Explanation

To answer this question, we need to understand the format of the TIME parameter in the context of job scheduling.

In job scheduling, the TIME parameter is used to specify the time at which a job is to be executed. The format of the TIME parameter is typically HHMM, where HH represents the hours and MM represents the minutes.

In this case, we want the job to run within 7 minutes and 30 seconds. To represent this in the TIME parameter format, we need to convert the time to hours and minutes.

7 minutes and 30 seconds can be converted to 0 hours and 7 minutes (since there are 60 seconds in a minute).

Now, let's go through each option to determine the correct answer:

Option A) TIME(07,30) - This option is correct because it represents the time as 07:30, which corresponds to 7 minutes and 30 seconds.

Option B) TIME(00,07,30) - This option is incorrect because it represents the time as 00:07:30, which includes hours, minutes, and seconds. The question specifies that the job should run within 7 minutes and 30 seconds, not hours, minutes, and seconds.

Option C) TIME(07:30) - This option is incorrect because it uses a different delimiter (":") instead of a comma (",") to separate the hours and minutes. The TIME parameter format requires a comma as the delimiter.

Option D) TIME(30:7) - This option is incorrect because it represents the time as 30:7, which does not follow the standard HHMM format. The hours should be represented in two digits (0-23) and the minutes should be represented in two digits (0-59).

Therefore, the correct answer is A) TIME(07,30). This option correctly represents the time as 07:30, which corresponds to 7 minutes and 30 seconds.

Express $5\dfrac {2}{3} hrs$ in minutes.

  1. $235\ mins$

  2. $320\ mins$

  3. $340\ mins$

  4. $523\ mins$


Correct Option: C
Explanation:

$5\dfrac {2}{3} hrs = \dfrac {17}{3}hrs$
$1\ hr = 60\ mins$
$\therefore \dfrac {17}{3} hrs = \dfrac {17}{3} \times 60\ mins = 340\ mins$.

Convert $2$ hours into minutes.

  1. $60\ min$

  2. $30\ min$

  3. $90\ min$

  4. $120\ min$


Correct Option: D
Explanation:

$1$ hour $=60$ minutes


$2$ hours $=2\times 60=120$ minutes

So option $D$ is correct.

What decimal of an hour is a second?

  1. $.0002\overline 9$

  2. $.00022\overline 8$

  3. $.0002\overline 7$

  4. $.0002\overline 6$


Correct Option: C
Explanation:

Given that one hour,

Now,

$1$ hour=$60\times 60$ second

$ 1s=\dfrac{1}{60\times 60}h $

$ =0.0002777777... $

$ =0.0002\overline{7} $

Hence, this is the answer.

$21$ months are equal to how many years?

  1. $1$

  2. $1\dfrac{1}{2}$

  3. $1\dfrac{3}{4}$

  4. $2$


Correct Option: C
Explanation:

$1$ year $=12$ months 

$1$ month $=\dfrac{1}{12}$ years
$21$ months $=\dfrac{1}{12}\times21=\dfrac{7}{4}=1\dfrac{3}{4}$
So option $C$ is correct.

State 'T' for true and 'F' for false.
(I) $12$ hours $:30$ hours $=8$km $:20$km
(II) The ratio of $1$ hour to one day is $1:1$
(III) The two terms of a ratio can be in two different units.

  1. (I)-T, (II)-T, (III)-T

  2. (I)-F, (II)-F, (III)-F

  3. (I)-T, (II)-F, (III)-F

  4. (I)-F, (II)-T, (III)-F


Correct Option: C
Explanation:

$i)$ $12$ hours $:$ $30$ hours$=8Km:20Km$

$\cfrac{12}{30}=\cfrac{2}{5}$ hours.
$\cfrac{8}{20}=\cfrac{2}{5}$ Km.
Hence, $True.$
$ii)$ The ratio of $1$ hour to $1$ day,
$\cfrac{1\quad hour}{1\quad day}=\cfrac{1}{24}\quad hours\neq 1$
Hence, $false.$
$iii)$ The two terms of a ratio can not be in two different units.
Hence, $false$.
$(I)-T, (II)-F,(III)-F$

A clock gains 5 minutes every hour.Then the angle traversed by the seconds hand in one minute will be 

  1. $390^0$

  2. $380^0$

  3. $360.5^0$

  4. $360^0$


Correct Option: A
Explanation:

Gain in 60 min=5min
in 1 min =$\dfrac{5}{60}min=\dfrac{5}{60}\times 60 sec=5 sec$
Angle traversed by second hand=$360^0+\dfrac{5}{60}\times 360^0=390^0$

$3$ hour $12$ minutes is equal to how many seconds?

  1. $10521\ seconds$

  2. $10510\ seconds$

  3. $11520\ seconds$

  4. $10600\ seconds$


Correct Option: C
Explanation:

$3$ hr $12$ min $=3\times 60\times 60+12\times 60$

$=3600\times3+720$ s
$=10800+720$ s $=11,520$ s

Which of these months does not have $31$ days?

  1. July

  2. March

  3. August

  4. November


Correct Option: D
Explanation:

$\Rightarrow$ All the 12 months have 31 or 30 days.

$\Rightarrow$  31 in case of January, March, May, July, august, October, December & 30 in case of April, June, September, November.
$\therefore$  $November$ does not have $31$ days.

How many seconds does an hour has?

  1. $3600$

  2. $600$

  3. $360$

  4. $60$


Correct Option: A
Explanation:

As we know, $1$ hour $=60$ minutes
and $1$ minute $=60$ seconds
So, $1$ hour $=60\times 60=3600$ seconds.
Hence, an hour has $3600$ seconds.
