    मायन शून्य के लिए एक विशेष प्रतीक का उपयोग करने वाले सबसे प्रारंभिक लोगों में से थे। उनकी प्रणाली में, शून्य के लिए यह प्रतीक किस आकार का था:

    • A. bar / रेखा
    • B. dot / बिंदु
    • C. shell / शंख
    • D. cross / क्रॉस
    Solution

    The Mayans used a shell shape for zero, while a dot stood for $1$ and a bar for $5$.

    मायनों ने शून्य के लिए एक शंख के आकार का उपयोग किया, जबकि एक बिंदु $1$ के लिए और एक रेखा $5$ के लिए थी।

  2. Q2. The Egyptian system has separate symbols for $1$, $10$, $100$ and so on, and a number is written by repeating these symbols. How many symbols in all are needed to write $324$?

    मिस्री प्रणाली में $1$, $10$, $100$ इत्यादि के लिए अलग-अलग प्रतीक होते हैं, और एक संख्या इन प्रतीकों को दोहराकर लिखी जाती है। $324$ लिखने के लिए कुल कितने प्रतीकों की आवश्यकता होती है?

    • A. $324$
    • B. $6$
    • C. $9$
    • D. $3$
    Solution

    $324$ needs $3$ hundred-symbols, $2$ ten-symbols and $4$ one-symbols, so $3 + 2 + 4 = 9$ symbols.

    $324$ के लिए $3$ सौ-प्रतीक, $2$ दहाई-प्रतीक और $4$ इकाई-प्रतीक चाहिए, इसलिए $3 + 2 + 4 = 9$ प्रतीक।

  3. Q3. Which Roman numeral correctly represents the number $49$?

    कौन-सा रोमन अंक संख्या $49$ को सही ढंग से दर्शाता है?

    • A. $XXXXIX$
    • B. $XLIX$
    • C. $IL$
    • D. $LIX$
    Solution

    $49 = 40 + 9 = XL + IX = XLIX$, using the subtractive rule for both $40$ and $9$.

    $49 = 40 + 9 = XL + IX = XLIX$, जिसमें $40$ और $9$ दोनों के लिए घटाव के नियम का उपयोग किया गया है।
