The Roman numeral for $1000$ is

  1. $V$

  2. $L$

  3. $D$

  4. $M$


Correct Option: D
Explanation:

Roman numeral for $1000$ is $M$

Roman numeral for the greatest three digit number is

  1. IXIXIX

  2. CMIXIX

  3. CMXCIX

  4. CMIC


Correct Option: C
Explanation:
The largest $3$ digit number is $999$. Let's convert that into Roman numerals.

$M = 1000, D = 500, C = 100, X = 10, V = 5$ and $I = 1.$

$900 = CM$

$90 = XC$

$9 = IX$

$900+90+9=999$
$(1000-100)+(100-10)+(10-1)$

Therefore, $999 = CMXCIX$
$(1000-100)+(100-10)+(10-1)$

Let's crossverify,
$CMXCIX=(1000-100)+(100-10)+(10-1)$
$=900+90+9=999$

Numerals that cannot be subtracted in Roman system are

  1. $V, L $ and $ D$

  2. $I, X$  and $ V$

  3. $C$

  4. $M$


Correct Option: A
Explanation:

We can only subtract powers of ten ($I, X,$ or  $C$ , but not  $V$  or $L$)

Hence, Numerals that cannot be subtracted in Roman system are $V, L$ and  $D$.

Hindu-Arabic numeral for MCDXVIII is

  1. 1618

  2. 1405

  3. 1418

  4. 1481

1000+(500-100)+10+5+3=1418 

Numerals that can be repeated in Roman system are 

  1. $I, X \ and\  C$

  2. $I, V \ and\  X$

  3. $V, L\   and\  D$

  4. $D$


Correct Option: A
Explanation:

As per the rules of writing Roman numbers, Only $I, X, C$, and  $M$  can be repeated; $ V, L$ , and $ D$  cannot be repeated.

Hence, Numerals that can be repeated in Roman system are  $I, X \ and \ C $

Roman numeral for the greatest single digit number is  

  1. XI

  2. IC

  3. IX

  4. ID


Correct Option: C
Explanation:

$IX=9$

X can be subtracted from

  1. $L$ and $ C$

  2. $D$  and $ M$

  3. $D $ only

  4. $M $ only


Correct Option: A
Explanation:

While writing Roman Numbers, do not subtract a number from one that is more than  $10$  times greater (that is, you can subtract  $1$  from $10 [IX]$  but not $ 1$  from $ 20$  there is no such number as $ IXX.)$
Hence,$ X (10)$  can be subtracted from $ L (50) \ and \ C (100)$

Write $39$ in roman numbers

  1. XXXIX

  2. XXXXI

  3. XXXX

  4. None of these


Correct Option: A
Explanation:
To convert $39$ to Roman Numerals we need to split it up into place values (ones, tens, hundreds, etc.), like this:

Place Value Number Roman Numeral
Tens            $30$ $XXX$
Ones               $9$ $IX$


Please note, we skipped place values that equal 0.

You then combine them all together (starting from the top) to get $XXXIX.$
So option A is the correct answer.

Roman numerals for $498$

  1. CDCXVIII

  2. CDCXIV

  3. CDXCVIII

  4. CDXCVII


Correct Option: C
Explanation:

The Roman numerals are represented by the following letters:

I = 1

V = 5

X = 10

L = 50

C = 100

D = 500

M = 1000

If a numeral is followed by another numeral of lower denomination, the two are added together;

if it is preceded by one of lower denomination, the smaller numeral is subtracted from the greater.

400 + 90 + 8 = CDXCVIII

$CDXCVIII=498$

Roman numeral for $2440$ is 

  1. $MMCDXL$

  2. $MCDXL$

  3. $MMMDXL$

  4. $MMDLX$

$M=1000,C=100,X=10 ,I=1$
$2440=2000+400+40$
          $=2000+(500-100)+(50-10)$
          $= MM    CD    XL$
$2440 = MMCDXL$

  1. I

  2. V

The product obtained when $13$ is multiplied by $7$(in roman number ) is 

  1. XXCI

  2. LXI

  3. XCI

  4. CI


Correct Option: C
Explanation:
 $13\times 7=91$
Break the number $91$ (decompose it) into place value subgroups: 
$91 = 90 + 1;$

Convert each subgroup: $90 = 100 - 10 => C - X = XC; 1 = I;$

Wrap up the Roman numeral: 
$91 = 90 + 1 = XC + I = XCI;$
$ XCI$ is a group of numerals in additive and subtractive notation which will be $91.$

So option C is the correct answer.

Roman numerals for $498$ is given by:

  1. $COCXVIII$

  2. $COCXIV$

  3. $CDXCVIII$

  4. $COXCVII$


Correct Option: C
Explanation:

$\Rightarrow$  The given number is $498.$

$\Rightarrow$  In Roman numbers $I=1,\,V=5,\,X=10,\,C=100$ and $D=500$.
$\Rightarrow$  $498=400+90+8$      [ Breaking the number into place value of subgroups ]
$\Rightarrow$  $400=500-100=D-C=CD$
$\Rightarrow$  $90=100-10=C-X=XC$
$\Rightarrow$  $8=5+1+1+1=V+I+I+I=VIII$
$\Rightarrow$  Now adding all the Roman numeral.
$\therefore$   $498=400+90+8=CD+XC+VIII=CDXCVIII$
$\therefore$   Roman numerals for 498 is $CDXCVIII.$
