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

- 16 ✓ Correct
- 17
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:
- Division: $91 \div 7 = 13$
- Multiplication: $4 \times 6 = 24$
- Rewrite Equation: $24 - 13 + 5$
- 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?
$4 \div 6 + 91 \times 7 - 5 = ?$

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:
- भाग (Division): $91 \div 7 = 13$
- गुणा (Multiplication): $4 \times 6 = 24$
- समीकरण अब: $24 - 13 + 5$
- जोड़/घटाव: $11 + 5 = 16$
इसलिए, सही उत्तर 16 है।
