Question (English)

What will come in place of the question mark (?) in the following equation if '+' and '$\div$' are interchanged and '$\times$' and '$-$' are interchanged?
$$4 - 12 + 3 \div 12 \times 6 = ?$$

  1. 11
  2. 46
  3. 13
  4. 22 ✓ Correct
Explanation:

According to the question, we need to interchange the signs:

  • Replace '+' with '$\div$' and vice versa.
  • Replace '$\times$' with '$-$' and vice versa.

The original equation is: $4 - 12 + 3 \div 12 \times 6$

After interchanging the signs, the new equation becomes:

$$4 \times 12 \div 3 + 12 - 6$$

Now, applying the BODMAS rule:

  1. Division ($12 \div 3$): $4 \times 4 + 12 - 6$
  2. Multiplication ($4 \times 4$): $16 + 12 - 6$
  3. Addition ($16 + 12$): $28 - 6$
  4. Subtraction ($28 - 6$): $22$

Thus, the correct answer is 22.

प्रश्न (हिंदी)

निम्नलिखित समीकरण में प्रश्नवाचक चिन्ह (?) के स्थान पर क्या आएगा यदि '+' और '$\div$' को आपस में बदल दिया जाए और '$\times$' और '$-$' को आपस में बदल दिया जाए?
$$4 - 12 + 3 \div 12 \times 6 = ?$$

  1. 11
  2. 46
  3. 13
  4. 22
स्पष्टीकरण:

प्रश्न में दिए गए निर्देशों के अनुसार, हमें चिह्नों को आपस में बदलना होगा:

  • '+' और '$\div$' को आपस में बदलें।
  • '$\times$' और '$-$' को आपस में बदलें।

मूल समीकरण है: $4 - 12 + 3 \div 12 \times 6$

चिह्नों को बदलने के बाद नया समीकरण होगा:

$$4 \times 12 \div 3 + 12 - 6$$

अब, BODMAS नियम का उपयोग करके इसे हल करते हैं:

  1. भाग (Division): $12 \div 3 = 4$
    समीकरण बन जाएगा: $4 \times 4 + 12 - 6$
  2. गुणा (Multiplication): $4 imes 4 = 16$
    समीकरण बन जाएगा: $16 + 12 - 6$
  3. जोड़ (Addition): $16 + 12 = 28$
    समीकरण बन जाएगा: $28 - 6$
  4. घटाव (Subtraction): $28 - 6 = 22$

अतः, सही उत्तर 22 है।
