यदि ‘\(\times\)’ और ‘+’को आपस में बदल दिया जाए तथा ‘\(\div\)’ और ‘-‘ को आपस में बदल दिया जाए तो निम्नलिखित समीकरण में प्रश्न चिह्न (?) के स्थान पर क्या आएगा?
\(66 – 11 \times 10 + 2 \div 14 = \)?
Detailed Solution & Logic
Correct Answer:
12
Given:
$66 - 11 \times 10 + 2 \div 14$
Interchange the operators:
$\times \leftrightarrow +$
$\div \leftrightarrow -$
So the equation becomes:
$66 \div 11 + 10 \times 2 - 14$
Using BODMAS:
= 6 + 20 - 14= 12
Answer: 12
