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.
