Q5. If all the prime numbers in the above arrangement are dropped, which of the following will be the sixth from the left end?
(a) 8
(b) 9
(c) 4
(d) 6
(e) None of these
Solutions (1-5):
S1. Ans. (e)
S2. Ans. (e)
S3. Ans. (b)
Sol. fifth to the right of the eight from the left end of the above arrangement= 5+8=13th from left end= 9
S4. Ans. (a)
Sol. 4th to the right of the 12th from right means = 12-4= 8th from the right, i.e., 1.
S5. Ans. (b)
Sol. 9
Frequently asked questions
What is the setup of this Coding-Decoding Type 2 puzzle?
A grid of digits is given, and you answer questions based on patterns of adjacency, like finding odd numbers immediately preceded by an even number and followed by an odd number.
What's an example question from this set?
One question asks how many odd numbers in the arrangement are immediately preceded by an even number and immediately followed by an odd number.
Does the puzzle involve positional counting too?
Yes, it also asks things like which number is the fifth to the right of the eighth from the left end, and the fourth to the right of the twelfth from the right end.
What skill does this question type test?
It tests careful, methodical scanning of a number sequence for positional and adjacency patterns without making counting errors under time pressure.
