### Twisted Ones Data Interpretation (DI) for IBPS/BOM

This year we've observed major changes in Banking examination's pattern and level. Quantitative Aptitude is one of the scoring subject if one has practiced it properly. As not many days are left for IBPS PO and BOM Examsthere comes a need to step up the level of preparation as well.

And to meet the need of the hour, here we give you Twisted Ones of Maths.

These set of questions will help you prepare for the unexpected.

Directions (1-6): Answer the questions based on the following information.
Help Distress (HD) is an NGO involved in providing assistance to people suffering from natural disasters. Currently, it has 37 volunteers. They are involved in three projects: Tsunami Relief (TR) in Tamil Nadu, Flood Relief (FR) in Maharashtra and Earthquake Relief (ER) In Gujarat. Each volunteer working with Help Distress has to be involved in at least one relief work project.
A maximum number of volunteers are involved in the FR project. Among them, the number of volunteers involved in FR project alone is equal to the volunteers having additional involvement in the ER project
The number of volunteers involved in the ER project alone is double the number of volunteers involved in all the three projects.
17 volunteers are involved in the TR project.
The number of volunteers involved in the TR project alone is one less than the number of volunteers involved in ER project alone.
Ten volunteers involved in the TR project are also involved in at least one more project.

Q1. Based on the information given above, the minimum number of volunteers involved in both FR and TR projects, but not in the ER project is-
(a) 1
(b) 3
(c) 4
(d) 5
(e) Can’t be determined

Q2. Which of the following additional information would enable to find the exact number of volunteers involved in various projects?
(a) Twenty volunteers are involved in FR
(b) Four volunteers are involved in all the three projects
(c) Twenty three volunteers are involved in exactly one project
(d) No need for any additional information
(e) None of these

Q3. After some time, the volunteers who were involved in all the three projects were asked to withdraw from one project. As a result, one of the volunteers opted out of the TR project ,out of the ER project, while the remaining ones involved in all the three projects opted out of the FR project. Which of the following statements, then necessarily follows?
(a) The lowest number of volunteers in Now, in TR project
(b) More volunteers are, now in FR project as compared to ER project
(c) More volunteers are, now in TR project as compared to ER project
(d) None of these
(e) Can’t be determined

Q4. After the withdrawal of volunteers, as indicated in Question 3, some new volunteers joined the NGO. Each one of the them was allotted only one project in manner such that, the number of volunteers working in one project alone for each of the three projects became identical. At that point, it was also found that the number of volunteers involved in FR and ER projects was the same as the number of volunteers involved in TR and ER projects. Which of the projects, now has the highest number of volunteers?
(a) ER
(b) FR
(c) TR
(d) Cannot be determined
(e) None of these

Q5. How many volunteers are working in all three projects initially?
(a) 4
(b) 8
(c) 12
(d) 7
(e) None of these

Q6. How many Volunteers are working in ER project alone?
(a) 4
(b) 8
(c) 12
(d) 7
(e) None of these

Directions (7-10): Answer the questions based on the following information.
Venkat, a stockbroker, invested a part of his money in the stock of four companies…. A, B, C, D. Each of these companies belonged to different industries, viz, Cement, Information Technology (IT), Auto and Steel, in no particular order. At the time of investment, the price of each stock was Rs. 100. Venkat purchased only one stock of each of these companies. He was expecting returns of 20%, 10%, 30% and 40% from the stock of companies A, B, C and D, respectively. Returns are defined as the change in the value of the stock after one year, expressed as a percentage of the initial value. During the year, two of these companies announced extraordinarily good results.

As a result, the returns on the stocks of these two companies were higher than the initially expected returns. For the company belonging to the cement or the IT industry with extraordinarily good results, the results were twice that of the initially expected returns.
