The sum of two integers is $ -278 $. If one of them is $ -156 $, then the other is
(i) $ -100 $
(ii) $ -122 $
(iii) 122
(iv) 100

Given: 

The sum of two integers is $-278$ and one of them is $-156$.

To do: 

We have to find the other integer.

Solution: 

Let the required integer be $a$.

According to the question,

$a + (-156) = -278$

$a = -278 -(- 156)$

$a=-278+156$

$a=-(278-156)$

$a=-122$

The other number is $-122$.
