If ‘4’ and ‘5’ are interchanged, what will come in place of question mark (?) in the following equation?
यदि ‘4’और ‘5’ को आपस में बदल दिया जाए, तो निम्नलिखित समीकरण में प्रश्न- चिह्न (?) के स्थान पर क्या आएगा?
\(20\div 4 + 5 \times 10\) = ?
Detailed Solution & Logic
Correct Answer:
44
Given expression:
$20 \div 4 + 5 \times 10$
Since 4 and 5 are interchanged, replace:
- $4 \rightarrow 5$
- $5 \rightarrow 4$
New expression:
$20 \div 5 + 4 \times 10$
Apply BODMAS:
$20 \div 5 = 4$
$4 \times 10 = 40$
Now add:
$4 + 40 = 44$
Answer: 44
