Reasoning Ability

In a 7-person circular arrangement with given constraints: A-C-D arrangement clockwise, E is 3rd right of A (which is 4th left, so 2 positions left of A in a 7-circle). Working through all constraints systematically places G immediately to the left of E.

If Mohan faces south on north side, his left is west. Priya is to his immediate left, so she's on the west side

Order: Rohan > Priya (85) > Anjali > Vikram. Priya is 2nd, but if Anjali could equal Priya's score, ambiguity exists. Standard interpretation: Rohan 1st, Priya 2nd, Anjali 3rd. Answer should be B. Rechecking: Rohan > Priya > Anjali > Vikram, so 3rd is Anjali

Y's mother = Z's wife (Z is Y's father). X's father = Y's brother = Z's son. So X is Z's grandson

We know: Arun > Bhavna, Arun > Dev, Arun > Chitra > Esha, Dev > Esha. Between Bhavna and Esha, we cannot definitively say who is shorter

From conditions: E is heaviest. F < A < G < D < C < B. Therefore B is second heaviest.

Differences: -1, -2, -3, -4, -5. Next difference is -5, so 90 - 5 = 85

Each number is of the form 2^n - 1: 2^2-1=3, 2^3-1=7, 2^4-1=15, 2^5-1=31, 2^6-1=63, 2^7-1=127

In a circle of 8, opposite positions are 4 apart. If B is 2 clockwise from A, B is 2 counter-clockwise from E

Differences: 1, 2, 3, 4, 5. So next difference is 5, therefore 20+5=25
