Direction: In the following question, a given questions is followed by...
Given that
Four subjects: History, Geography, Economics and Computer were taught in four consecutive periods of one hour each starting from 9.00 a.m.
From statement I: Economics period ended at 11.00 a.m. which was preceded by Computer.
We cannot determine with the statement.
Therefore, Statement I alone is not sufficient to answer the question.
From statement II: History was scheduled in the last period.
We cannot determine with the statement.
Therefore, Statement II alone is not sufficient to answer the question.
From statement III: Economics period was immediately followed by Geography.
We cannot determine with the statement.
Therefore, Statement III alone is not sufficient to answer the question.
By combining I and II
We conclude that Economics period began at 10.00 a.m. and Computer period began at 9.00 a.m. and History period began at 12 p.m.
So, the Geography period began at 11.00 a.m.
Therefore, the statements I and II together are sufficient to answer the question.
By combining I and III
We conclude that Economics period ended and Geography period began at 11.00 a.m.
Therefore, the statements I and III together are sufficient to answer the question.
By combining II and III
No relation between the two statements.
Therefore, the statements II and III together are not sufficient to answer the question
Therefore, the statements I and III together are sufficient to answer the question.
By combining II and III
No relation between the two statements.
Therefore, the statements II and III together are not sufficient to answer the question.
Hence, the statements either only I and II or only I and III are sufficient
