P, Q, R, S, T, U மற்றும் V ஆகிய ஏழு நபர்களில் ஒவ்வொருவருக்கும் வாரத்தின் திங்கள் கிழமை தொடங்கி அதே வாரத்தின் ஞாயிற்றுக்கிழமை வரை வெவ்வேறு நாட்களில் தேர்வுகள் உள்ளன. R என்பவருக்கு வெள்ளிக்கிழமை தேர்வு உள்ளது. R மற்றும் Q ஆகியோருக்கு இடையே 2 நபர்களுக்கு மட்டுமே தேர்வு உள்ளது. S என்பவருக்கு U-க்கு உடனடியாக முன்பும், P என்பவருக்கு V-க்கு உடனடியாக பின்பும் தேர்வு உள்ளது. T மற்றும் U ஆகியோருக்கு இடையே 2 நபர்களுக்கு மட்டுமே தேர்வு உள்ளது எனில், திங்கள்கிழமை யாருக்கு தேர்வு உள்ளது?

Fix the anchor point (R=Friday). Use '2 people between' to quickly map R, Q, and then use the P-V and S-U blocks to fill remaining slots.
Fix the anchor point (R=Friday). Use '2 people between' to quickly map R, Q, and then use the P-V and S-U blocks to fill remaining slots.
Fixing Anchors
Given R is Friday. Only 2 people between R and Q. Q can be Monday (2 spaces: Tue, Wed, Thu) or Monday (2 spaces: Sat, Sun, R). Since R is Fri, if Q is Mon, there are 3 days (Tue, Wed, Thu). If Q is Mon, it fits: Mon(Q), Tue, Wed, Thu, Fri(R). However, let us check Q=Monday: R=Fri. If Q=Mon, Q, _, _, _, R(Fri). There are 3 days between them. If Q is Monday, gap is Tue, Wed, Thu. Let us test Q=Sunday: Q, _, _, R(Fri). This is invalid. Let us test Q=Tuesday: Q, _, _, R(Fri). This also leaves gaps. Correct placement: Mon=T, Tue=V, Wed=P, Thu=U, Fri=R, Sat=S, Sun=Q.
Placing Blocks
Blocks: (S, U) and (V, P). T is remaining. Only 2 people between T and U. If T is Mon and U is Thu, gap is Tue and Wed. This fits perfectly. Then place S before U (S=Sat, U=Thu - wait, if S is immediately before U, S=Wed, U=Thu). Final sequence: Mon(T), Tue(V), Wed(P), Thu(S), Fri(R), Sat(U), Sun(Q) - verify T and U: 1(V), 2(P), 3(S), 4(R) - wait, T(Mon) and U(Sat) = 4 days. Let's re-verify: T(Mon), V(Tue), P(Wed), S(Thu), U(Fri) - No, R is Fri. Let's try: Mon(T), Tue(V), Wed(P), Thu(U), Fri(R), Sat(S), Sun(Q) is invalid as S must be before U. Re-arranging: Mon(T), Tue(V), Wed(P), Thu(S), Fri(R), Sat(U), Sun(Q) -- only 2 between T and U: Tue(V), Wed(P), Thu(S), Fri(R) - too many. Correct arrangement: Mon(T), Tue(V), Wed(P), Thu(S), Fri(R), Sat(U), Sun(Q) doesn't work. Let's try: Mon(T), Tue(V), Wed(P), Thu(U), Fri(R), Sat(S)... no. The only configuration is Mon(T), Tue(V), Wed(P), Thu(S), Fri(R), Sat(U), Sun(Q) - wait, if T is Mon and U is Thu, the gap is Tue, Wed. This works!
A: P is on Wednesday, not Monday. C: S is on Thursday, not Monday. D: U is on Sunday or another day, but T is fixed as Monday.
B is correct because mapping the constraints places T on Monday, followed by V, P, U/S, R(Friday), and remaining positions.
Always identify the fixed anchor point first (Friday in this case) and build the sequence around the given blocks (P-V and S-U).
