Answer:
A)128
B)717
Step-by-step explanation:
In Roman numerals each letter have a numerical value in Hindu-Arabic numerals.
These values are:
I = 1
V = 5
X = 10
L = 50
C =100
D = 500
M = 1000
a) CXXVIII = 100+10+10+5+1+1+1 = 128
b) XCDCCCXXVII = 500+100+100+10+10+7-100-10 = 717
In this question we subtracted the value of XC(-100-10) because it was preceding or appeared before a larger value and hence, we subtract these values from the value of DCCCXXVII(500+100+100+100+10+10+7).
This could be understood with the help of following example: If we calculate the value of CD it would be (500-100) = 400. Now, XCD = (400-10) = 390.
