(d) none of these
Solution: Correct option is (b) 13
Because 5 – ( – 8) = 5 + 8 = 13.
14. The sum of two integers is – 25. If one of them is 30 then the other is
(a) 55
(b) 5
(c) – 55
(d) none of these
Solution: Correct option is (c) – 55
Let x be the other integer.
x + 30 = –25
⇒ x = –25 – 30
⇒ x = –55
15. The sum of two integers is 20. If one of them is – 5 then the other is
(a) 25
(b) – 25
(c) 15
(d) none of these
Solution: Correct option is (a) 25
Let the other integer be x
x + (-5) = 20
⇒x - 5 = 20
⇒x = 25
16. The sum of two integers is – 13. If one of them is 8 then the other is
(a) – 5
(b) – 21
(c) 21
(d) none of these
Solution: Correct option is (b) – 21
Let the other integer be x.
x + 8 = −13
=> x = −13 − 8
=> x = −21
17. On subtracting – 8 from 0, we get
(a) – 8
(b) 8
(c) none of these

(a) – 15
(b) – 3
(c) 3
(d) none of these
Solution: Correct option is (c) 3
−6 − (−9)
= −6 + 9

24. On subtracting – 5 from 10, we get
(a) 5
(b) – 15
(c) 15
(d) none of these
Solution: Correct option is (c) 15
10 − (−5)
= 10 + 5
