Question 59.

Match Column I with Column II.

$\begin{array}{cccc}& \text{Column I}& & \text{Column II}\\ \text{(i)}& \text{The additive inverse of +2}& \text{(a)}& 0\\ \text{(ii)}& \text{The greatest negative integer}& \text{(b)}& -2\\ \text{(iii)}& \text{The greatest negative even integer}& \text{(c)}& 2\\ \text{(iv)}& \text{The smallest integer greater than every negative integer}& \text{(d)}& 1\\ \text{(v)}& \text{Sum of predecessor and successor of -1}& \text{(e)}& -1\end{array}$

Answer 1

(i) The additive inverse of a number x is the number that when added to x yields zero. It is obtained by reversing the sign of the number. The additive inverse of 2 is -2.

(ii) The greatest negative integer is -1.

(iii) The greatest negative even integer is -2.

(iv) The smallest integer greater than every negative integer is 0.

(v) Sum of predecessor and successor of -1 is -2.

The predecessor of a number is obtained by subtracting one from the number.

The successor of a number is obtained by adding one to the number.

The predecessor of -1 = -1 - 1 = -2

The successor of -1 = -1 + 1 = 0

Now, sum of -2 and 0 = -2 + 0 = -2

Hence, the correct matching is

(i) $\to$ b (ii) $\to$ e (iii) $\to$ b

(iv) $\to$ a (v) $\to$ b
