1. (c) Using Statement I: 5. d; Using Statement I: The gender of F is not known
Q > R > S > T > P, So, we cannot says if F is granddaughter or grandson
Q is the heaviest of B.
Using Statement II: The name of B has not even
Using Statement II: been mentioned. Using both statements together.
Q> R > S > T > P,
6. (c) From the statements II and III:
Q is the heaviest. T ⇔ w
2. (b) Using Statement I: We cannot determine if all the (+) (–)
fiends are facing the centre.
A is the facing outside of C is facing the centre of
circle. So all friends are not facing the centre. M
3. (c) Using Statement I: Though, sex of M is not known, it is given in statement
III, that T has three children only one of them is boy.
Monday Botany
Therefore, we may conclude that W has two
Tuesday Mathematic
daughters.
Wednesday Physics
7. (d) From Using Statement I:
Thursday Chemistry E > B > A

Friday Zoology From Using Statement II:
Chemistry is not taught on Wednesday > > > C > >
Using Statement II: From Using Statement III: Now combining all the
above statements, we have
Monday Botany/Zoology
E > B > A > C > D > F
Tuesday Mathematic
8. (e) From Using Statement II: From Using Statement
Wednesday Physics III: Now combining statements I and II J is in south-

Thursday Chemistry west direction from W
Friday Zoology 9. (e) Even by combining all the statements we cannot
find the day of the week on which Suresh’s mother
Or visited Suresh’s house.
Monday Botany/Zoology 10. (a) From Using Statement I and III:

Tuesday Mathematic Now or never again torn ka na sa ...(i)
Wednesday Physics again go now or never na ho ka sa ...(ii)
Thursday Chemistry From (i) and (ii) code for ‘go’ is ‘ho’
Friday Zoology/Botany 11. (a) From I: There are two possible arrangements.

Chemistry is not taught on Wednesday (a) P T R S
4. (c) Using Statement I: If the time is 9 o’clock now (b) P T R S
then after 30 minutes ie at 9:30 the angle between So, either T or R
the minute hand and hour hand cannot be 90˚. So, From II: There are two possible arrangements.
now time is not 9 o’clock
(a) Q T S
Using Statement II: If the time is 9 o’clock now then (b) T S Q
15 min before the hour and minute hand of the clock
can never coincide with each other Instead they will Again either T or S
have an angle of 7.5˚. So, the time now is not 90˚’ Combining I and II
clock. 12. (a) Using Statement I:
Using Statement II:
