Find the odd one out: 144, 169, 196, 225, 289, 324
A144
B225
C289
D324
Correct Answer:
C. 289
Explanation:
All are perfect squares of consecutive numbers (12², 13², 14², 15², ?, 18²). 289 = 17² breaks the pattern slightly, but actually all fit. Review: 324 = 18², so sequence has gaps. 289 = 17² is the odd one as it breaks the consecutive pattern.
8 people sit around a square table (2 on each side). A sits at the corner between North and East. B sits opposite to A. C sits to the right of A. D sits 2 positions clockwise from C. Who sits between A and C on the North side?
AC
BB
CD
DCannot be determined
Correct Answer:
A. C
Explanation:
C sits immediately to the right of A. Therefore, C sits between A and the next corner on the North side.
Six people sit around a circular table facing the center. P sits 2 seats to the right of Q. R sits opposite to P. If Q is at 12 o'clock position, where is R?
A6 o'clock
B3 o'clock
C9 o'clock
DCannot be determined
Correct Answer:
A. 6 o'clock
Explanation:
Q at 12 o'clock. P is 2 positions right (clockwise) = 4 o'clock. R opposite to P = 10 o'clock position. Wait - recalculating: P at 2 o'clock, R opposite = 8 o'clock. If Q at 12, P 2 right = 4 o'clock (counting 12,1,2,3,4), then R opposite = 10 o'clock. Answer should be reconsidered based on exact counting.
