What will come in the place of ‘?’ in the following equation,
What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘–’ are interchanged and also ‘\(\times\)’ and ‘\(\div\)’ are interchanged?
यदि निम्नलिखित समीकरण मे ‘+’ और ‘-‘ को आपस मे बदल दिया जाए तथा \(\times\)और ‘\(\div\)’को भी आपस में बदल दिया जाए ‘?’ के स्थान पर क्या आएगा?
\(88-7 \div 65 \times 13+34=? \)
Detailed Solution & Logic
Correct Answer:
89
\(88-7 \div 65 \times 13+34=? \)
+ = -
$ \times = \div $
solution
= $ 88 + 7 \times 65 \div 13 - 34 = ?$
=$ 88 + 7 \times 5 - 34 = ?$
= 88 + 35 - 34 = ?
= 123 - 34
= 89
