Q: Round off 11,125 to the nearest thousand.

The given number is \$11,125\$. The ones place of the number is \$5\$, the tens place is \$2\$, the hundreds place is \$1\$ and the thousands place is \$1\$.Its digit at hundreds place is \$1\$, which is less than \$5\$. So, we replace each of the hundreds, tens and ones digits by \$0\$ and keep the other digits as they are.Therefore, the number \$11,125\$ is rounded off to nearest thousands as \$11,000\$.Hence, option A is correct.

Q: Roman numeral for the greatest three digit number is

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\$

Q: \$CDI+V+C+X\$ is equal to

(D) \$CDI+V+C+X\$\$401+5+100+10=516\$

Q: The ages in years of \$10\$ teachers of a school are-\$32, 41, 28, 54, 35, 26, 23, 33, 38, 40\$What is the age of the oldest teacher and that of the youngest teacher?

Arranging the ages in ascending order, we get-\$23, 26, 28, 32, 33, 35, 38, 40, 41, 54\$We find that the age of the oldest teacher is \$54\$ years and the age of the youngest teacher is \$23\$ years.

Q: Compare: \$9423816\$ and \$9423826\$

\$ 9423816 < 9423826\$ \$\because\$ At tens place, number \$9423826\$ has \$2\$ whereas in the same place, number \$9423816\$ has \$1\$.

Question 3

Roman numeral for the greatest three digit number is

Accepted Answer

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$

Question 4

$CDI+V+C+X$ is equal to

Accepted Answer

(D) $CDI+V+C+X$$401+5+100+10=516$

Question 5

Round off 24,500 to nearest thousands.

Accepted Answer

To round a number to the nearest thousand, the digit in hundreds place is considered. if it is greater than or equal to 5 we round it up and  if is less than 5 we round it down.In $24,500$  the hundreds place is $5$ and the thousands place is $4$.Hence, increase the digit at thousands place by $1$ and replace each one of the digits in hundreds, tens and ones place by $0$$\therefore 24,500$ is rounded off to nearest thousands as $25,000.$
