Question

Four of the following five are alike in a certain way as per the given arrangement and hence form a group. Find the one who doesn’t belong to that group.

• A. The one who uses Docomo
• B. The one who uses Jio
• C. The one who uses Airtel
• D. The one who uses BSNL
• A. L
• B. The one who goes immediately before N
• C. I
• D. The one who goes on 26^th August

Answer 1

The Correct Option is D

The problem revolves around organizing six individuals according to given constraints and identifying the odd one out from a set of options. We need to determine the arrangement of people based on the given conditions and identify the person who doesn't fit the pattern within the group formed.

Let's break it down logically: 

1. Since N goes on an odd-numbered date and there are three months with two dates, N must be in one of these dates: July 11th, August 11th, or September 11th.
2. Two persons go between the one who uses Vodafone and N, so we consider N on 11th of a month and place Vodafone on the 26th afterward.
3. K and J go on the same date, but not in September, so possible dates for K and J together are 11th or 26th of July or August.
4. The one who uses Aircel goes immediately before J, which indicates Aircel is directly before K and J.
5. M does not go in July, and a balance of persons before and after M, relative to the one using Docomo, needs to be achieved.
6. I goes immediately after the one who uses BSNL. Since there is only one person between Jio and BSNL, and neither M nor L uses Jio, it becomes a basis to arrange remaining.

By combining all these conditions, we get a specific arrangement:

Name	Date	Month	Network
N	11th	July	Aircel
K	11th	August	Airtel
J	11th	August	Jio
I	26th	August	Docomo
M	11th	September	Vodafone
L	26th	September	BSNL

Now, given the options:

• The one who uses Docomo
• The one who uses Jio
• The one who uses Airtel
• The one who uses BSNL

The sequence highlights that each person besides the one using BSNL is linked with having a specific relationship about date or adjacency (for instance, Jio is with Airtel on the same date). The one who uses BSNL (L) stands out as not forming a specific link with others as per the arrangement dictating "forming a group." Hence, L using BSNL disrupts the pattern and is identified as the one who doesn't belong to the group.

Answer 2

The problem requires arranging people and their tour dates according to specific conditions. We'll use the following method to find out who uses the Airtel network: 

1. Based on the information, N tours on an odd-numbered date. Hence, N goes either July 11 or September 11.
2. Only two persons are between Vodafone and N, meaning one possibility is Vodafone on July 26, N on September 11, and then another person somewhere in between.
3. K and J share the same date but not in September, implying they go either on July 11 or August 11.
4. The person with Aircel goes before J but not in August, so it's on July 11 or 26.
5. The same people go after M and before the one who uses Docomo, which means M can only go on August 26 if considering the current layout.
6. M isn't in July, so likely dates for M align with September or August, but with our deduction, August 26 suits these conditions.
7. BSNL and Jio have one intervening person and I will follow BSNL. Aligning people and networks sets BSNL on August 11 and J on August 26 (with their matching network, say Docomo).
8. August 26, thus far, aligns L and Airtel placement due to how lists are structured, complying with the rest of criteria.

Based on these deductions, the complete assignment places the Airtel user on August 26, meaning the person using Airtel is indeed the one who goes on 26^th August.
