Test: Roman Numerals- 1 - Question 4

Which of the following options is written in the ascending order?

Detailed Solution for Test: Roman Numerals- 1 - Question 4
  • XCVII = XC + VII = 90 + 7 = 97
  • CXCIV = C + XC + IV = 100 + 90 + 4 = 194
  • DCCLXVIII = DCC + LX + VIII = 700 + 60 + 8 = 768
  • MDCLXII = M + DC + LX + II = 1000 + 600 + 60 + 2 = 1662

So, 97 < 194 < 768 < 1662
Hence, the correct ascending order is XCVII < XCCIV < DCCLXVIII < MDCLXII.

Test: Roman Numerals- 1 - Question 5

Which of the following numerals is equal to CDXLVIV + CXV?

CDXLIV
= CD + XL + IV
= 400 + 40 + 4
CXV
= 100 + 10 + 5
= 115
Now, 444 + 115 can be solved as

444 + 115 = 559
Now, 559
= 500 + 50 + 9
= D + L + IX = DLIX
Hence, CDXLIV + CXV = DLIX

Test: Roman Numerals- 1 - Question 8

Which of the following options is equal to MMMCCLXXV − MCCCXXIV?

Detailed Solution for Test: Roman Numerals- 1 - Question 8

MMMCCLXXV
= MMM + CC + LXX + V
= 3000 + 200 + 70 + 5
= 3275
MCCCXXIV
= M + CCC + XX + IV
= 1000 + 300 + 20 + 4
= 1324
3275 − 1324 can be solved as

Therefore,
3275 − 1324 = 1951
But, 1951
= 1000 + 900 + 50 + 1
= M + CM + L + I
= MCMLI
Hence,  MMMCCLXXV − MCCCXXIV = MCMLI
 

Test: Roman Numerals- 1 - Question 9

Which of the following options is true?

Detailed Solution for Test: Roman Numerals- 1 - Question 9

A. XCVIII = XC + VIII = 90 + 8 = 98
MCVIII = M + C + VIII = 1000 + 100 + 8 = 1108
Which means XCVIII < MCVIII.
Hence, the statement XCVIII > MCVIII is false.
B. DCVIII = DC + VIII = 600  + 8 = 68
MCVIII = 1108
Hence, the statement DCVIII < MCVIII is true.
C. DCVIII = 68 MCVIII = 1108
Which means DCVIII < MCVIII.
Hence, the statement DCVIII = MCVIII is false.
D. XCVIII = 98
LXXXVIII = LXXX + VIII = 80 + 8 = 88
Which means XCVIII > LXXXVIII.
Hence, the statement XCVIII < LXXXVIII is false.
