Open in App
Solution
The correct option is B 60
−13+(−69)+57−(−89)−(53+(−49))
=−13−69+57+89−(53−49)
=−13−69+57+89−(53−49)
=−13−69+57+89−53+49
Now, first take all negative numbers and then take all positive numbers, and then add them.
=(−13−69−53)+(57+89+49)
=−135+195
=60
(Since 195 > 135, the result will be positive).
−13+(−69)+57−(−89)−(53+(−49))
=−13−69+57+89−(53−49)
=−13−69+57+89−(53−49)
=−13−69+57+89−53+49
Now, first take all negative numbers and then take all positive numbers, and then add them.
=(−13−69−53)+(57+89+49)
=−135+195
=60
(Since 195 > 135, the result will be positive).
