**NUMBER TEST**

In this type of questions, generally a set, group or series of numerals is given and the candidate is asked to trace out numerals following certain given conditions or lying at specific mentioned positions after shuffling according toacertain given pattern.

**SOLVED EXAMPLES **

**Ex.1**. How many such 5’s are there in the following number sequence each of which is immediately

preceeded by 3 or 4 but not immediatly followed by 8 or 9.

**3 5 9 5 4 5 5 3 5 8 4 5 6 7 3 5 7 5 5 4 5 2 3 5 1 0**

(a) None (b) Three (c) Four (d) Five (e) None of these.

**Sol**. As you know, a number which comes after a given number is said to follow it while the one which comes before the given number proceeds It.

Thus, the number satisfying the given conditions may be marked as follows :

**35954 [5] 53584 [5] 673 [5] 7554 [5] 23 [5] 1 0**

Clearly, there are five such 5’s. Hence, the answer is d. : 7

**Ex.2**. In the series given below, how many eights are there each of which is exactly divisible by its immediate preceding as well as succeeding numbers ?

**2 8 3 8 2 4 8 2 4 8 6 8 2 8 2 4 8 3 8 2 8 6**

(a) One (b) Two (c) Three (d) Four (e) None of these.

**Sol**. Clearly, we may mark such set of three numbers, in which the middle number is 8 and each of the two numbers on both sides of it, is a factor of 8, as Shown below

28382 [482] 4868 [282] 4838286. so, there are two such 8’s. Hence, the answer is b.

Ex.3. If it is possible to form a number with the second, the 5th and the 8th digits of the number 3 1 5 4

9 78 6, which is perfect square of a two digit even number, which of the following will be the 2nd digit

of that even number ?

(a) 1 (b) 4 (c) 6 (d) No such number can be formed (e) None of these.

Sol. The 2nd, 5th and 8th digit of the number 31549786 are 1, 9 and 6 respectively. The perfect square of two digit even number, formed using the digit 1, 9 and 6 is 196. and, 196 is equal to 14^{2} so, the required even numberis 14. Clearly, its second digit is 4. Hence the answer is b.
