Question

P, Q, R and S are four different integers on a number line. From the following clues, find these integers and write them in ascending order.

i) S is the least of the given integers.
ii) R is the smallest positive integer.
iii) The integers P and S are at the same distance from 0.
iv) Q is 2 units to the left of integer R.

Answer 1

According to the clues, plotting the points on a number line, we get

As S is the least of the given integers, it is placed at the left most end.

Since R is the smallest positive integer, it is placed next to the right of 0.

As Q is 2 units to the left of R it is placed as the left next number of 0.

P and S are at the some distance from 0. P is placed opposite to S.

∴ Ascending order: S < Q < 0 < R < P.
