1 11 20 28 35 __ __ 50 53
Correct Answer
D. 41Â Â Â Â Â 46
Explanation
The given sequence follows a pattern where each number is the sum of the two previous numbers. Starting with 1, the next number is 1 + 11 = 12. Continuing this pattern, the next number is 12 + 20 = 32, then 32 + 28 = 60, and finally 60 + 35 = 95. The missing numbers should follow the same pattern, so the answer is 95 + 5 = 100 and 95 + 9 = 104. Therefore, the missing numbers are 100 and 104.

Arii si Darii sunt doua triburi rivale. Fiecare dintre ei incearca sa captureze cat mai multi membrii ai tribului inamic. Stiind ca, indiferent de conditii, toti Darii dorm numai 5 ore pe noapte, Arii au atacat satul atunci cand acestia dormeau si au capturat 10 prizonieri. Dupa 3 zile, seful tribului Ari observa ca toti prizonierii dorm mai mult de 5 ore pe noapte.
Care este concluzia care poate fi dedusa cu necesitate din informatiile de mai sus?
Correct Answer
A. Niciun prizonier nu este Dari
Explanation
The conclusion that can be deduced from the given information is that no prisoner is a Dari. This can be inferred because the Ari tribe attacked the village when the Dari people were sleeping, and they captured 10 prisoners who are now observed to be sleeping more than 5 hours per night. Since all Dari people only sleep 5 hours per night, it can be concluded that none of the prisoners are Dari.
