Question

There are XXIV boys and XXII girls in a class. What is the total number of students in the class?

• A. XXXXIIIV
• B. XLIV
• C. XLVI

Answer 1

The correct option is C XLVI

Number of boys = XXIV
Number of girls = XXII
Total number of students = Number of (girls + boys) = XXIV + XXII

Step 1: Write the Roman numerals as Hindu Arabic Numerals.
XXIV = 10 + 10 + 4 = 24
XXII = 10 + 10 + 2 = 22

Step 2: Add the numbers.
XXIV + XXII = 24 + 22 = 46
Total number of students = XXIV + XXII
= 46

Step 3: Write the result in Roman numerals.
46 = 40 + 6 = XL + VI
= XLVI

Therefore, the number of students in the class is XLVI.
