Directions : Read the following information carefully and answer the following questions.
Eight persons P, Q, R, S, T, U, V, and W live in a building of eight floors such that the topmost floor is numbered as 8 and the lowermost floor is numbered as 1 but not necessarily in the same order. They shop on eight different e-commerce websites viz. Flipkart, Ajio, Myntra, Jabong, Amazon, Shopclues, Jiomart, and Tata Cliq but not necessarily in the same order.
The one who shops on Flipkart lives immediately above the one who shops on Shopclues. Neither V nor P shops on Flipkart, Tata Cliq and Myntra. Three persons live between V and S, who lives below V and also does not shop on Jabong. Only three persons live between W and R, who shops on Amazon. R lives on one of the even numbered floor above W and Q, who does not shop on Flipkart and Myntra and also does not live on the second floor. Two persons live between Q and the one who shops on Jabong. Two persons live between the one who shops on Jabong and the one who shops on Ajio. The number of persons living between the one who shops on Jabong and R is same as the number of persons living between the one who shops on Ajio and P. T lives on one of the floors below U. Both W and Q live on the even numbered floor.

V
- B.

Show answer & explanation
Correct answer: E
Concept
In a floor-arrangement puzzle, pin the most constrained people first, but do not assume the floors are fully fixed before the secondary clues are used. Floor clues and shop clues are interlocking: when the floor clues alone leave a few people interchangeable, the shop clues (here, the platform-spacing conditions) feed back and pin the remaining floors. Solve until every position is forced, then read off the asked-for person - the one who shops on JioMart.
Application: the floors that the position clues force
R is on an even floor, three persons sit between W and R, and R is above both W and Q. R must be even and above both W and Q; combined with the platform-spacing clues below, this pins R on floor 6 and W on floor 2 (the R=8, W=4 alternative fails those spacing checks).
Three persons sit between V and S with S below V, which - once the platform clues are applied - settles V on floor 7 and S on floor 3.
Q is on an even floor, is not on floor 2, and lies below R, so Q is on floor 4.
That leaves floors 1, 5 and 8 for P, T and U. 'T below U' alone does NOT yet fix them - several orders still fit, so the floors are not fully determined by the position clues by themselves.
Application: the shop clues finish the grid
R (floor 6) shops Amazon, given directly.
Two persons sit between Q (floor 4) and the Jabong shopper, so Jabong is on floor 7 or floor 1; the Jabong-to-Ajio spacing and the equal-count clue rule out floor 1, fixing Jabong on floor 7, i.e. V (V is allowed Jabong, since V is barred only from Flipkart, Tata Cliq and Myntra).
Applying the Jabong-to-Ajio spacing together with 'persons between Jabong and R equals persons between Ajio and P' places Ajio on floor 4, so Q shops Ajio; and 'Flipkart immediately above Shopclues' plus the remaining bans constrain the lower-floor platforms.
Resolving these platform constraints is what finally pins the still-open trio: it forces P onto floor 5 (with T on floor 1 and U on floor 8), and the only platform left for floor 5 is JioMart.
Therefore P is on floor 5 and shops on JioMart.
Cross-check
One valid completion (top to bottom): U-8 (Tata Cliq), V-7 (Jabong), R-6 (Amazon), P-5 (JioMart), Q-4 (Ajio), S-3 (Flipkart), W-2 (Shopclues), T-1 (Myntra).
Every spacing clue checks out: 3 between V and S, 3 between W and R, 2 between Q and Jabong, and the matching counts for Jabong/R vs Ajio/P.
The JioMart shopper is P, who is not one of the four named choices V, R, S, T - so 'None of these' is the matching answer.
Note: only the four lower-floor platforms — Flipkart, Shopclues, Myntra and Tata Cliq among S, W, T and U — admit more than one valid split; that flexibility never reaches floor 5, so the JioMart shopper stays fixed as P (floor 5) in every valid completion.
