Question

Match column A with column B

Column 1	Column 2
In integers, $2km$ above sea level is indicated by	$-99$
Integer between $-5$ and $-3$	$-6$
Predecessor of $-18$	$+2km$
The value of $-\left|8-2\right|$	$-19$
Smallest negative integer of two digits	$-4$

Answer 1

(A) The value of above sea level is always indicated by a positive sign. So $2km$ above sea level indicates $+2km$.

Thus, (A) matches to $\left(III\right)$

(B) The integer lying between $-5$ and $-3$ is $-4$

Thus, (B) matches to $\left(V\right)$

(C) The predecessor of $-18$ can be found by subtracting $1$ from it. The predecessor of $-18=-18-1=-19$

Thus, (C) matches to $\left(IV\right)$

(D) We know that, $-\left|8-2\right|=-\left|6\right|=-6$

Thus, (D) matches to $\left(II\right)$

(E) The smallest two digit negative integer is the opposite of largest two digit positive integer. So it is $-99$

Thus, (E) matches to $\left(I\right)$
