1. C)
Given Number:Â Â Â Â  4Â  2Â  1Â  5Â  7Â  9Â  3Â  6Â  8
Ascending order:Â  1Â  2Â  3Â  4Â  5Â  6Â  7Â  8Â  9
Hence the required pairs are 4-9, 1-2 and 3-6
2. A)
Â
3. B)
Given number: 7 3 4 6 2 8 5
Ascending Number: 2 3 4 5 6 7 8
Â
4. D)
We have to find out even number – even number – odd number sequence.
Â
There are four such such even numbers: 6,8,2 and 8.
Â
5. A)
The new number formed is 4Â  3Â  0Â  1Â  8Â  2Â  7Â  9Â  6Â  5
The seventh digit from the left is 7, the 3rd digit from the left of 7 is 1
Â
6. A)
Given Number:Â Â Â Â Â  2 5 6 7 3 9 4 8
Ascending order:Â  2 3 4 5 6 7 8 9
Specified letters are 6 and 4 respectively.
Therefore, required sum = (4 + 6 =) 10
7. E)
8. A)
9. D)
10. C)
11. C)
12. B)
13. C)The given words are as follows:
LAP BUT CAR SON HID
When positions of first and third alphabets of each of the words are interchanged, we have
PAL TUB RAC NOS DIH
Clearly, PAL and TUB are the only meaningful words. These words are obtained from LAP and BUT respectively.
Â
14. D)After making necessary changes, we have
KBQ AVS BBQ RPO GJC
Clearly, there are three words in which no vowel appears. These words are KBQ, BBQ and GJC.
Â
15. E) When the second alphabet in each of the word is changed to the next alphabet in the English alphabetical order, we have
LBP BVT CBR NPS HJD
Clearly, in all the above five words, there is no vowel.Â
