Locating a stated fact
The survey covered 1,840 households across four blocks. Of these, 612 reported at least one member working outside the district, and 209 reported remittances as their main source of income. The remaining households were classified as locally dependent, a category the survey does not define further.
Option by option
A612
That is the number reporting a member working outside the district, which is a different question.
B209
Stated directly in the second sentence.
C1,228
The remainder after 612, which the passage calls locally dependent. Arithmetic the passage did not ask for.
D1,840
The total surveyed.
Carry this forward
A fact question has its answer in the passage as a word or a figure. If you are calculating, you have moved to a different question — check whether the number you want is simply printed.
