In a code, STABLE is written as 19-20-1-2-12-5. How is MOBILE written?
Seven students P, Q, R, S, T, U, V stand in a line. T is 4th from left. P is 2 positions to the left of T. V is 2nd from right. Q is between P and S. Where is R?
Answer: A
T at 4, P at 2, V at 6 (2nd from right in 7). Q between P(2) and S: possibly 3. Remaining: R at 5 or 7. V at 6 means R at 5 or 7. Given Q between P and S, arrangement: P-Q-S-T-?-V-R gives R at 6, or P-Q-S-T-R-V-U gives R at 5. Correcting: R at position 6.
Q.55Medium
All doctors are intelligent. Some intelligent people are rich. Conclusion: Some doctors are rich. Is this conclusion valid?
Answer: B

In a logic puzzle, 6 boxes are arranged left to right. Red box is 3 positions from left. Green is 2 right of Yellow. Blue is immediate left of Red. If there are only 4 colors, where is Yellow?
Answer: A
Red at 3, Blue at 2. Green 2 right of Yellow: if Yellow at 1, Green at 3. But Red at 3. If Yellow at 4, Green at 6. This works: Blue(2), Red(3), Yellow(4), Green(6). Yellow at position 4... Rechecking: Yellow could be at 1 if Green at 3, but Red there. So Yellow at 4.
