Answer 1

The correct option is C

M

CCCXXV + DCLXXV : Combining all the letters we get
D CCCC L XXXX VV
The VV can be written as X ,So the number becomes
D CCCC L XXXXX
Now, the XXXXX can be written as L ,So the number becomes
D CCCC LL
Now the LL can be written as C, so the number becomes
D CCCCC
Now the CCCCC can be written as D, so the number becomes
DD, which is nothing but M.

So, CCCXXV + DCLXXV = M.
