What will come in the place of the question mark
What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘-‘ are interchanged and ‘\(\times\) and ‘\(\div\)’ are interchanged?
यदि निम्नलिखित समीकरण मे ‘+’ और ‘-‘ को आपस बदल दिया जाए और ‘ $\times $ और ‘$ \div $’ को आपस में बदल दिया जाए, तो निम्नलिखित समीकरण में प्रश्न चिह्न (?) के स्थान पर क्या आएगा?
\(21 – 7 \div 144 \times 3 + 18 = \) ?
Detailed Solution & Logic
Correct Answer:
339
On change of sign
$21 +7\times 144\div 3 - 18 $= ?
= $21 + 7 \times 48 - 18 $ = ?
= 21 + 336 -18
= 336 + 21- 18
=336 + 3
Answer = 339
