[#42] Question : In a certain code, 'nop al ed' means They like flowers'. Which code word means 'flowers' ? Statements : I. 'id nim nop' means 'They are innocent'. II. 'gob ots al' means 'We like roses'.
Correct Answer
I alone is sufficient while II alone is not sufficient
Explanation
Solution: In the given statement and I, the common word is 'They' and the common code word is 'nop'. So, 'nop' is the code for 'They'. In the given statement and II, the common word is 'like' and the common code word is 'al'. So, 'al' is the code for 'like'. Thus, in the given statement, 'ed' is the code for 'flowers'.
[#43] Question : What is the code for 'mangoes' in the code language ? Statements : I. In that code language, 'Te Le Pa Na' means 'You eat many mangoes' and 'Le Na Da' means 'You sell mangoes'. II. In the code language, 'Ge Na Se La Le' means 'They eat bananas and mangoes' and 'Ne De Le La' means 'Who others eat bananas'.
Correct Answer
I alone is sufficient while II alone is not sufficient
Explanation
Solution: In 'You eat many mangoes' and 'Who others eat bananas', the common word is 'eat' and the common code word is 'Le'. So, 'Le' means 'eat'. In 'You eat many mangoes' and 'They eat bananas and mangoes', the common code word 'Le' stands for 'eat'. So, the other common code word 'Na' stands for the other common word i.e. 'mangoes'.
[#44] Question : In a row of five children A, B, C, D and E, who is standing in the middle ? Statements : I. D is to the immediate right of E and B is to the immediate left of E. II. B is at the extreme left of the row.
Correct Answer
I alone is sufficient while II alone is not sufficient
Explanation
Solution: From I, we have the order: B, E, D. From II, B is at the extreme left of the row. Thus, considering both I and II, we conclude that among the five children, D is the third and hence the middle child in the row.
[#45] Question : How many employees of Bank Z opted for VRS ? Statements : I. 18% of the 950 officer cadre employees and 6% of the 1100 other cadre employees opted for VRS. II. 28% of the employees in the age-group of 51 to 56 and 17% of the employees in all other age-groups opted for VRS.
Correct Answer
(A) I alone is sufficient while II alone is not sufficient
Explanation
Solution: From I, we have: number of employees who opted for VRS = 18% of 950 + 6% of 1100 = 171 + 66 = 237. From II, we cannot get the required answer until and unless the number of employees in age-group 51 to 56 and other age-groups is known.
