9) There are three jars E, F, and G containing marbles. Each jar contains different number of marbles. How many marbles are there in jar E?

Statements:

I)Â If three marbles are transferred from jar F to jar E, then both the jars will have equal number of marbles.

10) Â In the month of January eight people â€“ A, B, C, D, E, F, G and H have their birthdays on different dates â€“ 2, 4, 5, 7, 10, 25, 29, 31 (not necessarily in the same order). What is the date of Bâ€™s birthday?

Statements:

I)Â Bâ€™s birthday is neither on 10 nor on 29. Aâ€™s birthday is on the last date of January.

II)Â Bâ€™s birthday date is a perfect square. Câ€™s birthday date is not a prime number but comes before 10.

III) Â Bâ€™s birthday comes in between of Eâ€™s and Fâ€™s birthday.

A) Insufficient data

B) Only I is sufficient

C) Only II is sufficient

D) Only III is sufficient

E) Only I and III are sufficient

Directions (1-5) :

B, D, K and L sits at corner of the square whereas R, X, V and S sits at middle of the square.

B sits third to the left of the one who was born in March. Only one person sits between R and the one who was born in March.

The one who is the eldest person sits second to the right of L. B is not the eldest.

The one who was born in July sits second to the left of V. R was born before June. V was born in a month of 30 days.

The one who was born in April sits immediate right of K. K was born in a month which has less than 31 days.

Case 1B will be dropped because K was born in a month which has less than 31 days.

The one who was born in May sits second to the right of X.

Case 1A and 2B will be dropped because V was born in a month which has 30 days.

K is not the youngest. L was not born in a month which has 30 days.

Directions (6-8) :

Let us first decode the given symbols and then draw a family tree.

Let us check each of the options;

4) P @ M % N % K

Here, this expression means,

M is the mother of P. N is the sister of M. K is the sister of N.

The diagram will be as follows

Therefore, in this option K is the aunt of P.

Hence, option d is the one in which K is not grandaunt of P.

Expression F # T @ K % L @ O means that,

T is the father of F. K is the mother of T. L is the sister of K. O is the mother of L.

The diagram will be as follows

Therefore, clearly, O is the great-grandmother of F.

3) P * Q @ R * T

Here, this expression means,

Q is the brother of P. R is the mother of Q. T is the brother of R.

The diagram will be as follows

Clearly, T is the uncle of P in this option.

Directions (9-10) :

1) If three marbles are transferred from jar F to jar E, then both the jars will have equal number of marbles.

(Implies, jar F has 6 more marbles in it than jar E:

F â€“ E = 6)

2) Average of marbles in jar E and F is 53.

(Implies, total number of marbles in jar E and F is 106.

E + F = 106

By solving the above two equations, we will get:

E = 50 and F = 56)

Hence, both statement I and II are sufficient to answer the question.

From statement I:

Bâ€™s birthday is neither on 10 nor on 29. Aâ€™s birthday is on the last date of January.

Bâ€™s birthday could be on 2, 4, 5, 7, 25.

Therefore, statement I alone is not sufficient to answer the question.

From statement II:

Bâ€™s birthday date is a perfect square. Câ€™s birthday date is not a prime number but comes before 10.

Possible options for B â€“ 4 / 25.

Dates before 10 are 2, 4, 5 and 7 but 2, 5 and 7 are prime numbers. So, Câ€™s birthday is on 4th January.

Thus, Bâ€™s birthday is on 25.

Therefore, statement II alone is sufficient to answer the question.

From statement III:

Bâ€™s birthday comes between Eâ€™s and Fâ€™s birthday.

Nothing can be determined from this statement.

Therefore, statement III alone is not sufficient to answer the question.

On combining I and III:

Bâ€™s birthday could be on 2, 4, 5, 7, 25.

Therefore, statement I and III together are not sufficient to answer the question.

Hence, statement II alone is sufficient to answer the question.
