What will come in place of the question mark (?)
What will come in 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 मे बदल दिया जाए ‘\(\times\)’ और ‘\(\div\)’ को भी आपस में बदल दिया जाए ‘?’ के स्थान पर क्या आएगा,
\(4515 \times 5 -431 \div 3 + 821 =?\)
Detailed Solution & Logic
Correct Answer:
1375
\(4515 \times 5 -431 \div 3 + 821 =?\)
+= -
$ \times = \div $
change symbol
$4515 \div 5 + 431 \times 3 - 821 =?$
= 903 +1293 - 821
=2196 - 821
Answer = 1375
