In each of the following questions two statements are given and these statements are followed by two conclusions numbered (1) and (2). You have to take the given two statements to be true even if they seem to be at variance from commonly known facts. Read the conclusions and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.

Give answer:

  • (A) If only (1) conclusion follows
  • (B) If only (2) conclusion follows
  • (C) If either (1) or (2) follows
  • (D) If neither (1) nor (2) follows and
  • (E) If both (1) and (2) follow.

Yes, @Waheed.

It's correct because there is no cross between actor, dancer or singer.

Here, 2nd diagram is wrong one and instead of that, the three circles become intersect and the inside circle mentioned singers next circle mentioned dancers and outside circle mentioned actors, this should be right.

How first conclusion follows? I think either is the right answer.

@All.

Always solve from the conclusion. If both the statement have a common and all is attached with that common word. Then conclusion true. Ex here common is a singer. And singer Se pehele all he. So directly some actors are dancers. Next, for conclusion 2 we can't draw -ve conclusion from positive statements. So false.

@SUMAN

you repeated
B+A = Y.
B +B = no conclusion.
B+Z = Y.
B+Y= no conclusion.

B+A = Z.
B +B = Y.
B+Z = no conclusion.
B+Y= no conclusion.

Which combination is now correct?

Let A- all (eg- all trees are dog.)
B- all not (eg- all trees are not dog.)
Z- some (eg- some trees are dog.)
Y- some not(eg- some trees are not dog.)

A can be converted to Z(eg- All trees are dog. conversion- some trees are dogs. (or) some dogs are tree)
B can be converted to B or Y((eg- All trees are not dog. conversion- all dogs are not tree. (or) All trees are not dog))
Z can be converted to z(eg- some trees are dogs.conversion- some dogs are trees.)
Y has no conclusion.

Combination :
A+A = Z.
A +B = Z.
A+Z = no conclusion.
A+Y= no conclusion.

B+A = Y.
B +B = no conclusion.
B+Z = Y.
B+Y= no conclusion.

B+A = Z.
B +B = Y.
B+Z = no conclusion.
B+Y= no conclusion.

Y + (A, B, Z)= no conclusion.

Hi,

Can anyone explain it in short? Because I couldn't get the "some are not " model.

Statements:
All squares are circles.
All circles are units.
No circle is a meter.

Conclusions:

I. Some units which are not circles can be meters.
II. Some squares being meters is a possibility.

Anyone, please explain how to solve this using formula table.

2nd Venn diagram shows that all actors are dancers. Then, why option A is correct?
(1)

Roshan said:   7 years ago
In second diagram. All actors are dancer comes out. And in first some actors are dancers. If the statement is not satisfying both the diagrams, then how we can say one is correct?

Please explain.
