Question

Hindu-Arabic numeral of LXXXVI is

Accepted Answer

The Hindu-Arabic numeral of LXXXVI is 86. Let's break down the Roman numeral LXXXVI to understand why Option 3 is the correct answer:

1. **L** represents 50.
2. **X** represents 10. Since there are two X's following L, they add up to 20 (10 + 10).
3. **V** represents 5.
4. **I** represents 1.

When you add these values together, you get:

- L (50) + X (10) + X (10) + V (5) + I (1) = 86

Therefore, the Hindu-Arabic numeral for LXXXVI is indeed 86, which corresponds to Option 3.

Now, let's explain why the other options are incorrect:

- **Option 1: 95** - This is incorrect because the Roman numeral for 95 would be XCV, not LXXXVI. XCV is composed of XC (90) and V (5), which adds up to 95.

- **Option 2: 56** - This is incorrect because the Roman numeral for 56 would be LVI, not LXXXVI. LVI is composed of L (50), V (5), and I (1), which adds up to 56.

- **Option 4: 126** - This is incorrect because the Roman numeral for 126 would be CXXVI, not LXXXVI. CXXVI is composed of C (100), XX (20), V (5), and I (1), which adds up to 126.

In conclusion, the correct Hindu-Arabic numeral for LXXXVI is 86, making Option 3 the correct choice.
