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 ‘+’ और ‘-‘ को परस्पर बदल दिया जाए तथा ‘\(\times\) और \(\div\) को परस्पर बदल दिया जाए, तो निम्नलिखित समीकरण में प्रश्न चिह्न (?) के स्थान पर क्या आएगा?
\(98\div 7 + 288 \times 2 – 144 \times 3 – 152 \div 2 + 120 = ? \)
Detailed Solution & Logic
Correct Answer:
774
$ 98\div 7 + 288 \times 2 - 144 \times 3 - 152 \div 2 + 120 $= ?
+ = -
$ \times = \div $
change symbol
$ 98 \times 7 - 288 \div 2 + 144 \div 3 + 152 \times 2 - 120 $= ?
686 -144 +48 + 304 -120
590 + 304 -120
894 -120 = 774
Answer = 774
