Reasoning Ability Quiz For IBPS RRB PO Clerk Mains 2022- 9th September

Directions (1-5): In each of the questions given below, a group of letters is given followed by some combinations of number/symbol. You have to find out which of given combination correctly represents the group of letters based on the numbers/symbols codes and the conditions given below. If none of the given combinations represents the group of letters correctly, give (e) i.e. ‘None of these’ as the answer.

Condition for coding the group letters:
(i) If the first letter is vowel and last letter is consonant, the codes for the first and the last letter are to be interchanged.
(ii) If the first as well as the last letter is vowel, then both are to be coded by the code for the last letter.
(iii) If the first as well as the last letter is consonant, then both are to be coded by the code for the first letter.
(iv)If the first letter is consonant and last letter is vowel, the codes for the first and the last letter are to be coded as β.

Solutions

S1. Ans. (b)
Sol. Condition II is applied.

S2. Ans. (a)
Sol. Condition III is applied.

S3. Ans. (d)
Sol. Condition IV is applied.

S4. Ans. (c)
Sol. Condition I is applied.

S5. Ans. (b)
Sol. Condition III is applied.

S6. Ans. (b)
Sol. Given series – 5 H K 8 2 L P 7 D W F A I Z 31 5 G Q W R X T Z 4 9 6 M N
Hence, there is only one such number which is immediately preceded by prime number.

S7. Ans. (d)
Sol. Given series – 5 H K 8 2 L P 7 D W F A I Z 31 5 G Q W R X T Z 4 9 6 M N
After removing – 5 H 8 2 L P 7 D W F A I Z 31 5 G Q W R X T 4 9 6 M N
So, 15th element from the left end = 1

S8. Ans. (c)
Sol. Given series – 5 H K 8 2 L P 7 D W F A I Z 31 5 G Q W R X T Z 4 9 6 M N
Sixth alphabet from the left end = W
Eighth alphabet from the right end = Q
Hence, there are five alphabets between W and Q.

S9. Ans. (c)
Sol. Given series – 5 H K 8 2 L P 7 D W F A I Z 31 5 G Q W R X T Z 4 9 6 M N
So, required sum = 8 + 2 + 4 + 6 = 20.

S10. Ans. (d)
Sol. Given series – 5 H K 8 2 L P 7 D W F A I Z 31 5 G Q W R X T Z 4 9 6 M N
16th element from the left end = 1
So, 7th element to the right of 1 = T

Solution (11-15):
Sol. In each code, the number is the highest number representation of the letter in the word as per alphabetical series.
The letter is the alphabet (in the alphabetical series) of the number of letters in the word. Example: If there are four letters in the word, 4th letter in the alphabetical series is D
For example: ‘Profile’
The letter with the highest value in alphabetical series is R, which represents 18.
There are seven letters in the word, so 7th letter in the alphabetical series is G.
Therefore, the code for ‘profile’ is 18G

S12. Ans. (c)
S13. Ans. (d)
S14. Ans. (b)
S15. Ans. (b)
