Question (English)

What will come in the place of '?' in the following equation, if '$+$' and '$-$' are interchanged and '$\times$' and '$\div$' are interchanged?
$4 \div 6 + 91 \times 7 - 5 = ?$

  1. 12
  2. 21
  3. 16 ✓ Correct
  4. 17
Explanation:

Step-by-step Solution:

Given Equation: $4 \div 6 + 91 \times 7 - 5 = ?$

Interchanging signs:

  • Replace $\div$ with $\times$
  • Replace $+$ with $-$
  • Replace $\times$ with $\div$
  • Replace $-$ with $+$

New Equation:
$4 \times 6 - 91 \div 7 + 5$

Applying BODMAS rule:

  1. Division: $91 \div 7 = 13$
  2. Multiplication: $4 \times 6 = 24$
  3. Rewrite Equation: $24 - 13 + 5$
  4. Addition/Subtraction: $11 + 5 = 16$

So, the correct answer is 16.

प्रश्न (हिंदी)

यदि '$+$' और '$-$' को आपस में बदल दिया जाए और '$\times$' और '$\div$' को आपस में बदल दिया जाए, तो निम्नलिखित समीकरण में '?' के स्थान पर क्या आएगा?
$4 \div 6 + 91 \times 7 - 5 = ?$

  1. 12
  2. 21
  3. 16
  4. 17
स्पष्टीकरण:

चरण-दर-चरण हल:

दिया गया समीकरण: $4 \div 6 + 91 \times 7 - 5 = ?$

चिन्हों को बदलने पर:

  • $\div$ की जगह $\times$
  • $+$ की जगह $-$
  • $\times$ की जगह $\div$
  • $-$ की जगह $+$

नया समीकरण:
$4 \times 6 - 91 \div 7 + 5$

BODMAS नियम लागू करने पर:

  1. भाग (Division): $91 \div 7 = 13$
  2. गुणा (Multiplication): $4 \times 6 = 24$
  3. समीकरण अब: $24 - 13 + 5$
  4. जोड़/घटाव: $11 + 5 = 16$

इसलिए, सही उत्तर 16 है।
