Which among the following pairs of integers give -7 on addition ?

(a) - 13, 20 (b) -5, 12 (c) 15, -22 (d) 8, -1

Checking each of the options,

b) -5 + 12 = 7

c) 15 + (-22) = 15 - 22 = -7

d) 8 + (-1) = 8 - 1 = 7

Thus,

• It can be concluded that option c is correct answer. As 15 + (- 22) = - 7.
