What will come in place of the question mark (?)
What will come in place of the question mark (?) in the following equation if ‘+’ and ‘ $ \div $’ are interchanged and ‘$\times $’ and ‘–’ are interchanged?
यदि ‘+’ और ‘$ \div $’ को आपस में बदल दिया जाए और ‘$ \times $’ और ‘-‘ को आपस में बदल दिया जाए, तो निम्नलिखित समीकरण में प्रश्न चिह्न (?) के स्थान पर क्या आएगा?
$ 4 – 12 + 3 \div 12 \times 6 $= ?
Detailed Solution & Logic
Correct Answer:
22
$ 4 - 12 + 3 \div 12 \times 6 $= ?
change symbol
+ = $ \div $
$ \times $ = -
After interchange, the expression becomes:
$ 4\times 12 \div 3 + 12 - 6 $
16 + 12 - 6 = 22
Answer = 22
