Reasoning PYQs

Word is- D I S C I P L I N E

Vowels and then consonants arranged alphabetically- E I I I C D L N P S

Vowels replaced by the previous letter and consonants replaced by the next letter- D H H H D E M O Q T

Hence, the sixth letter from the right end here is D.

​Given: Nine persons were born on the same date and month of different years, i.e., 1969, 1971, 1973, 1976, 1979, 1984, 1990, 1999, and 2009. Their ages are calculated as per the base year 2025.

1. O is three years elder than P.
2. Only one person was born between O and N.
3. I is two years younger than N. 

Here, we have 2 Cases, i.e., Case 1 and Case 2.

 

4. More than three persons were born between N and U.
5. S is immediately younger than Z.
6. Z is three persons elder than W. H is not elder than U. 

So, Case 2 is eliminated. 

 

So, Case 1 is the final arrangement:

 

Five persons were born between H and O.

Hence, the correct answer is Five.

The least possible Venn diagram will be:

Conclusions:

I. Some hills are river → False (As we can see below some hills can be river is a possibility but not definite, So some hills are river is False).

II. Some deserts are hills → False (As we can see above some deserts can be hills is a possibility but not definite. So, some deserts are hills is False).

Hence, None follows.

The least possible Venn diagram will be:

Conclusions:

I. Some banana is potato → False ( As we can see it is possible but not definite. So some banana is potato is false).

II. Some fruits are not bananas → True (As we can see some fruits can never be banana. So some fruits are not bananas is true).

Important Points

Only few statement is a combination of two statement some and some not.

So when only few fruits are bananas is given. It means some fruits are bananas and some fruits are not banana.

Hence, Only II follows.

Possible Venn Diagram for given

Statements:

Conclusions:

Some flowers are stem. → False (as only leaves are flowers.)

No petal is flowers. → True (as only leaves are flowers.)

Hence, Only conclusion II is true.
