[#66] Question : Among A, B, C, D, E and F, who is the heaviest ? Statements : I. A and D are heavier than B, E and F but none of them is the heaviest. II. A is heavier than D but lighter than C.
Correct Answer

(A) I alone is sufficient while II alone is not sufficient

Explanation

Solution: From I, we conclude that since none of A and D is the heaviest and each one of B, E and F is lighter than both A and D, so C is the heaviest.

[#67] Question : How is 'No' coded in the code language ? Statements : I. 'Ne Pa Sic Lo' means 'But No None And' and 'Pa Lo Le Ne' means 'If None And But'. II. 'Le Se Ne Sic' means 'If No None Will' and 'Le Pi Se Be' means 'Not None If All'.
Correct Answer

(A) I alone is sufficient while II alone is not sufficient

Explanation

Solution: In the two statements given in I, the common words are 'But', 'None', 'And' and the common code words are 'Ne', 'Pa', ,'Lo'. So, 'Ne', 'Pa' and 'Lo' are codes for 'But', 'None' and 'And'. Thus, in the first statement, 'Sic' is the code for 'No'.

[#68] Question : Who is to the immediate right of P among five persons P, Q, R, S and T facing North ? Statements : I. R is third to the left of Q and P is second to the right of R. II. Q is to the immediate left of T who is second to the right of P.
Correct Answer

(C) Either I or II is sufficient

Explanation

Solution: From I, we have the order: R, -, P, Q. From II, we have the order: P, Q, T. Clearly, each one of the above two orders indicates that Q is to the immediate right of P.

[#69] Question : On which date of the month was Anjali born in February 2004 ? Statements : I. Anjali was born on an even date of the month. II. Anjali's birth date was a prime number.

Explanation

Solution: From I and II, we conclude that Anjali was born in February 2004 on a date which is an even prime number. Since the only even prime number is 2, so Anjali was born on 2nd February, 2004.
