$8,3,0,1$ .

0%
$1038$
0%
$1308$
0%
$1083$
0%
$0138$

Explanation

The ascending order of the given numbers

$8,3,0,1$ is:

$0 < 1 < 3 < 8$

A number cannot begin with

$0$ , so we will put it in the second place.

The smallest digit (other than

$0$ ) is

$1$ .

Therefore, the number will begin with

$1$ .

Thus, the smallest number formed is

$1038$ .

Hence, the smallest

$4$ digit number formed is

$1038$ .

Let us convert the given number in words into numerals as follows:

Eleven lakh

$=11,00,000$

Seventy thousand

$=70,000$

Six hunderd

$=600$

Seven

$=7$

Now, add the numerals as shown below:

$1100000+70000+600+7=1170607$

Explanation

The ascending order of the given numbers

$7,8,9,5$ is:

$5 < 7 < 8 < 9$

We observe that the smallest digit is

$5$ and the largest digit is

$9$ .

Therefore, the smallest number formed is

$5789$ .

But it is given that the number formed should have

$9$ at its hundredth place and

$8$ at its one's place, therfore, the required number is:

$5978$ where

$8$ is at one's place,

$7$ is at tens place,

$9$ is at hundredth place and

$5$ is at thousandth place.

Hence, the smallest

$4$ digit number formed is

$5978$ .

0%
$7512$
0%
$5217$
0%
$7125$
0%
$1275$

Explanation

An even number is an integer which is "evenly divisible" by two. This means that if the integer is divided by

$2$ , it yields no remainder.

(a)

$7512$ is divisible by

$2$ as

$\dfrac {7512}{2}=3756$ , so it is a four digit even number.

(b)

$5217$ is not divisible by

$2$ , so it is not a four digit even number.

(c)

$7125$ is not divisible by

$2$ , so it is not a four digit even number.

(d)

$1275$ is not divisible by

$2$ , so it is not a four digit even number.

Hence,

$7512$ is a four digit even number using the digits

$2,7,5,1$ .

$1280,1200,1000$

Explanation

$\Rightarrow$ Round off to 10 for 1289 is 1280 or 1290 but nearest to 1289 is 1290.

$\Rightarrow$ So, round off to the nearest

$10$ is

$1290$ .

$\Rightarrow$ Round off to 100 for 1289 is 1200 or 1300 but nearest to 1289 is 1300.

$\Rightarrow$ So, round off to the nearest

$100$ is

$1300$ .

$\Rightarrow$ Round off to 1000 for 1289 is 1000 or 2000 but nearest to 1289 is 1000.

$\Rightarrow$ So, round off to the nearest

$1000$ is

$1000$ .

$\therefore$ The answer is

$1290,\,1300,\,1000.$

$655=DCLV$

So option

$A$ is correct.

There is a rod of length

$4\ cm$ and another rod of length

$500\ mm$ has been joined to the first rod. Then the length of the rod(in cm) formed by joining these

$2$ is :

0%
$450\ cm$
0%
$54\ cm$
0%
$9\ cm$
0%
$4.5\ cm$

Explanation

Length of first Rod is

$4cm$

Length of second Rod is

$500mm$

Total Length of the Rod by joining these two rods is

$4cm$

$500mm$

We know that,

$1$

$centimeter =10$

$mm$ ,

$1$

$mm =\dfrac{1}{10}$

$cm$

We need to convert

$4$

$cm$

$500$

$mm$ to

$centimeter$

$4cm$

$500$

$mm$

$= 4cm + 500mm$

Now,

$500$

$mm =\dfrac{1}{10} \times 500$

$cm$

$= 50$

$cm$

$\therefore 4cm\ 500\ mm=4cm + 500mm=(4+50)cm$

$=54\ cm$

So, Option

$B$ is correct

Round-off

Explanation

The given number is

$13$

Its unit digit is

$3$ which is less than 5.

So, we replace unit digit by

$0$

$\therefore$ Rounding off 13 to nearest 10 gives

$10$ .
