My general awareness was somewhat poor and so to maintain the balance I worked really hard on Reasoning. I attempted 44/50 questions in SBI PO with 90% accuracy in a span of 35minutes. Now before you get any ideas, there's simply no tricks or shortcuts in Reasoning, there's only practise. Even so, I'm going to share how I handle each and every topic when it comes to Reasoning. Let's start with Venn Diagrams.
What are Venn Diagrams?
They are figures representing group of items in the form of circles (mostly).
Can I expect these questions?
Direct questions on Venn diagrams won't be asked in any of the SBI exams. You might find them in IBPS or SSC CGL. But we will be using these to solve syllogism questions in the next article, and questions on syllogism are asked in every exam, that too worth atleast 5 marks.
Situation - 1
When 1 group is completely included in the 2nd and 2nd is completely included in the 3rd. For eg. Guitarists, instrumentalists, musicians
Situation - 2
When 2 groups are unrelated to each other but are completely included in the 3rd. For eg. carrot, pumpkin, vegetable
Situation - 3
When 2 groups have something in common and both are completely included in the 3rd. For eg. Mothers, sisters, females. Some mothers can be sisters too and vice versa.
Situation - 4
When 1 group is completely included in another, while 3rd group is unrelated to both of them. For eg. Indians, Asians, Europeans
Situation - 5
When all 3 groups are related in some way but cannot be completely included in each other. For eg. Illiterate people, unemployed people, poor people. We can have a combination of any 2, and we can even have a combination of all 3.
Situation - 6
When 2 groups are unrelated to each other but they are both somewhat related to the 3rd. For eg. Police, Doctor, Female. We can have Female policemen and female doctors but police and doctors don't have anything in common.
Situation - 7
When 1 is completely included in the 2nd and both of them are party related to the 3rd. For eg. Females, Nieces, cousins. All nieces can only be females, but there can be female cousins and some female cousins can also be somebody's niece.
Situation - 8
If 1 group is partly related to the 2nd group and 3rd is completely unrelated to both of them. For eg. Students, scholars , books. Some students can be scholars but neither of them can be a book!
Situation - 9
When all 3 are completely unrelated. For eg. Sun, Pluto, Earth. Now, if there was another group "Planets" then Pluto and Earth would fit in there, but we can't add things of our own will, right?!
That's all the possibilities there can be while using Venn Diagrams. In case you're confused, just refer to the picture posted above, I'm sure it will clarify things for you.
QUESTIONAIRE
There's mainly 3 kinds of questions on Venn diagrams. I am posting sample questions on each of the 3. The answer keys have been added. Happy solving! :))
