IBM Placement Paper

It consist of mainly three sections.

a) Section 1 : Matrix Test

- No of question : 15 ( 13 minutes )

Note :  No negative marks for this section

b) Section 2 : Number Series Test

- No of question : 20 (15 minutes)

Note : Negative marking(1/4) is there for this section

c) Section 3 : Analytical type (Aptitude)

- No of question :12 (15 minutes)

Note : Negative marking(1/4) is there for this section.

This is the new pattern of IBM. This new pattern has been implemented. It contains 3 sections.

i) Section A

Some information is given in the form of matrices, with headings for rows as row1, row2 . Etc. For columns with headings as column1, column 2. Etc. Those matrices are as follows.

• Row1 @ * 2 Z
• Row2 S K ? \$
• Row3 I P Z +
• Row4 # 8 F Q
•

Questions are as follows ( not same questions but same type):

1. After giving similar type of conditions , what is the element left to H? In this section they gave around 4 matrices of this type and gave some questions for each matrix.

2. 5s then which column elements sum equals to 9?

3. If column1 , Column 4 are interchanged and row3 , row4 are interchanged and diagonal elements from top left to bottom right are written in reverse order then what is the element in row1 and column 1?

4. If a company produces 15 different model of tv sets of 2 inchs screen and 4 different model of 4 inches screen size. Then how many model should vendor has for all the model so that all models willdisplayed in the showroom?

5. If a team consists 20 members in which 20% are mathematician then how many member should they hire so that the ratio would become 10/11.

6. If Zs in odd numbered rows are replced with 7s and Ss in odd numbered columns are replaced with.

Section B

All questions in this section are from number series. Total number of questions are 20.Time limit is 4 minutes. These are also multiple choice questions( 5 options). Negative marking(1/4) is there for this section.
