Latest Infosys Aptitude Question SOLUTION: All pens are pencils. All pencils are ball. No pencils are ball. Some pens are pencils. All Pencils are Box. All boxes are pens. Option A) 654 B) 235 C) 214 D) 621 E)

A- 654 is right ans

@JAYASHREE BAL In this type of problems,generally first two are statements and last one is conclusion

654 is only the correct answer..

D)621 is the right choice according to me..

As we have to check two things(conditions).
1.the number of terms in the first two statements i.e if take A)654,first two statements are 6 and 5.
In 6 terms used are a)boxes b)pens and in 5 a)pencils b)box.so,total term used is 3.

Now,we have to check in third statement(conclusion statement) i.e 4,how many number of terms are there?We can see there are a)pens b)pencils i.e 2 terms..
so,term used in conclusion is 2 and term used is same as in 1st and 2nd,no different term is used..

so,this option satisfy first condition,if different term used in conclusion statement,then no need to check 2nd condition.this will be the wrong option.

>But it satisfies 1st so check for 2nd condition-
for this following conventions are used
1. UP+UP=UP
2. UP+UN=UN
3. UN+UP/PP=PN
4. PP+UP/UN=PP/PN

Here, UP and UN(universal +ve and -ve)-statement with All, every, any, none, not a single, only etc.

PP/PN(particular +ve/-ve)-Some, many, a few, not many, very little etc
So,for A)654
1st statement(6)=UP
2nd statement (5)=UP
conclusion statemnt(4)=PP
Here,
UP+UP=PP, which is incorrect,acc to convention it should be UP+UP=UP.
So,this is incorrect option.

So,like wise check for all options,only D)621 will satisfy the two condition.Hence D is correct one.

its d 621 all+all=all

yes,i got it,My answer is wrong because we cant take it for 4 things s0,answer will not be D)621 as there is no any relation between 6 and 2,and also 4 terms are there.
I have written the above method,which is applicable for only when three terms are in first two statement.
So, answer might be A)654,but i have confusion.

654 is the answer
In two sentences 'ALL' is there means conclusion statement will start with all/some and then remaining uncommon words of the sentences

please refer https://www.youtube.com/watch?v=DyRo1_ZCLFU . everyone can easily understand it

4-conclusion

refer this site -

125 wrong
621 is def wrong because 125 has 4 terms(pens,pencils,ball, boxes)
so we cant get aconclusion we should have only 3 terms to get a conclusion
in 621 also similarly has 4 terms which is not pssible....
ans was 654 according to the rules of deductions.

ITS very easy
1> all pens are pencils.
2>All pencils are ball
3> No pencils are ball.
4> Some pens are pencils
5>All Pencils are Box.
6> All boxes are pens.

now by using option u can solve ...
a) 6 5 4 = All boxes are pens. All Pencils are Box.Some pens are pencils.

hear eliminate common word box from above we left
==> all pens are pencils . & last statement proves that saying some pens are pecils.

so ans is 654

anyone explain me dis ??

C-214 is right ans

you can also refer below site to know and solve any type of syllogism-

http://mrunal.org/2013/01/reasoning-syllogism-all-cats-dogs-approach-shortcut-technique-explained-ibps-ssc-csat-cat.html#12065-statement24-conclusion

SURENDRA,
E)125,it satisfy UP+UP=UP i.e 2nd condition..But it does not satify the first condition as for two statement 1 and 2 terms used are a)pen,b)pencil,c)ball....and now for conclusion statement 5,a more term box is added..
so,it does not satify 1st condition.
Hence E)125 is wrong..

a.654 answer

plz mention which are statements n which r conclusions

654 is the correct answer because
in these all 6 sentences we need to take as below
take first two statements and 3rd one is conclusion and take 4th nd 5th as statements and 6th is the conclusion

plz explain me...

but chandhi mishra,in that case 125 also satisfies the ans
up+up=up

D-621. all boxes are pens-> all pens are pencils->all pencils are balls.

ans is E) 125 using ven diagram for each statement only statement 1 2 5 are right so ans is E

pls explain the solution

not understand this......statement 2 and statement 3 are opp to each other...so how we can....???

sol... 3 is correct...
