Question

To quickly revise addition of Roman Numerals, your teacher asked the class to add XX and XXX.
She gave you 4 options. Which circle would you choose?

• A. Circle A
• B. Circle B
• C. Circle C
• D. Circle D

Answer 1

The correct option is D

Circle D

XX = 10 + 10 = 20
XXX = 10 + 10 + 10 = 30
Thus, XX + XXX = 20 + 30 = 50.

The Roman numeral for 50 is L.

Thus, the circle to be chosen is D.
