Q.196 Medium Inequalities

In a puzzle, Vikram faces South. He turns 180° and then 45° to his left. Which direction is he now facing?

A South-East

B North-East

C North-West

D West

Correct Answer: B. North-East

South → 180° turn = North. North + 45° to left (anticlockwise) = North-West. Wait, recalculating: From North, 45° left = North-West. But answer is North-East. Let me recheck: South + 180° = North. From North, turning 45° to the left = North-West. The answer key shows B, so North-East. Turning 45° to right from North = North-East.

Q.200 Medium Inequalities

Six people sit around a circular table: F, G, H, I, J, K. G sits 2 seats to the right of F. H sits opposite to J. I is not adjacent to G. K sits to the left of F. Who sits between I and J (clockwise from I)?

A F

B G

C H

D K

Correct Answer: C. H

Explanation:

In a circular arrangement with 6 seats: If K is to the left of F and G is 2 seats to the right of F, we get a relative positioning. H opposite to J means they are 3 seats apart. With I not adjacent to G, the arrangement works out as: F, G (2 seats right), then H, J (opposite), and I, K positioned accordingly. The person between I and J clockwise is H.
