Question

The sum of two integers is − 23. If one of them is 18, then the other is

(a) −14 (b) 14 (c) 41 (d) −41

Answer 1

Sum of integers = − 23
One of the numbers = 18
Other number = (− 23) − (18)
= − 23 − 18
= − (23 + 18)
= − 41
Therefore, the other number is − 41.
Hence, the correct option is (d).
