Directions (9-10): In each of the following questions, various terms of an alphabet series are given with one or more terms missing as shown by (?). Choose the missing terms out of the given alternatives.
Q9. Z, U, Q, ?, L
Q10. A, CD, GHI, ?, UVWXY
By making the interchanges given in (a), we get the question as 2 – 5 + 3 = 4 or 0 = 4, which is false.
By making the interchanges given in (b), we get the equation as 3 – 2 + 5 = 4 or 6 = 4, which is false.
By making the interchanges given in (c), we get the equation as 5 – 3 + 2 = 4 or 4 = 4, which is true.
So, the answer is (c).
Sol. Clearly, nine days ago, it was Thursday.
∴ Today is Saturday.
Sol. The new number formed after rearrangement is 6 4 7 9 8 3 2 5
The seventh digit from the right end is 4. The third digit to the right of 4 is 8.
Sol. The given series when written in the reserve order becomes:
13, 11, 5, 0, 1, 2, 6, 4, 8, 3, 0, 7, 9, 3, 7
Then 7th number from the left is 6. The 4th number to the right is 6 is 0.
Sol. The letters, on rearrangement, form the word ‘ABHORRENCE’ meaning ‘Hatred’, the opposite of which is ‘Liking’.
So, the answer is (a).
Sol. Each term consist of consecutive letters in order. The number of letters in the terms goes on increasing by one at each step. Also, there is a gap of one letter between the last letter of the first term and the first term letter of the second term; a gap of two letters between the last letter of the second term and the first letter of the third term; and so on. So, there should be a gap of three letters between the last letter of the third term and the first letter of the desired term.
So , The answer is = MNOP
