About Data Sufficiency
This topic covers most of the topics of
reasoning i.e. alphabetical series, coding and
decoding, blood relation, direction, ranking
etc. In data sufficiency, we don’t have to find
an answer rather we have to analyze the
given data and decide whether the given
data is sufficient to find an answer or not.

question followed by two statements labelled

the question;

answer the question;
