Number Test and Ranking Test (Reasoning)

NUMBER TEST

In such test, generally you are given a
long series of numbers. The candidate
is required to find out how many times a number satifying the conditions specified in the question occurs.

EXAMPLE . How many 8s are there in the following number sequence which
are immediately preceded by 5 but not
immediately followed by 3?
3 8 5 8 4 5 8 3 9 8 8 5 8 8 8 9 3

Sol. Let use see the following:
3 8  5 8 4  5  8  3  9  8 8  5   8
8 8  9 3
Clearly, two such 8s are there.

Remember
There is no rule as how to attempt these
questions but we can practice these
questions:

RANKING TEST

Ranking involves determining the sequencial order of one or more
persons/objects based on comparison
of parameters such as height, weight,
age, length, position, merits etc. For comparison, generally following symbols are used:
(i) A>B (means A is greater/heavier/
taller/higher /more than B)
(ii) A<B (means A is smaller / lighter /
shorter / lower / less than B)

Questions based on ranking are generally given with a set of information in jumbled form based on which the candidates are
required to systematically arrange the given information and determine the sequencial order of arrangement of the various persons/objects.

EXAMPLE. N is more intelligent
than M. M is not as intelligent as Y. X is
more intelligent than Y but not as good
as N. Who is the most intelligent of all?
(a) N (b) M (c) X (d) Y
Sol.(a) According to the question,
N>M
Y>M
N>X>Y
On arranging the above data,
we get, N>X>Y>M
So, N is the most intelligent
among them.

EXAMPLE. Shailendra is shorter than Keshay but taller than Rakesh,Madhav is the tallest. Aashish is a little shorter than Keshav and little taller than Shailendra. If they stand in the order of increasing heights, who will be the second?
(a) Aashish (b) Shailendra (c) Rakesh (d) Madhav
Sol. (b) According to the question,
K>S>R
(K= Keshay
S=Shailendra
R= Rakesh
M = Madhav
A = Aashish)
Madhav is the tallest.
K>A>S
On arranging the above data,
we get,
M >K>A>S>R
or
R=1<S=2<A=3<K=4<M=5

Hence, Shailendra will be the
second.
