(A) Number of boys and girls are 7x and 8x respectively.
(B) Average age of boys = 12.2 years.
Average age of girls = 11.4 years.
(C) Number of girl- Number of boy = 2
From (A) and (C)
8x - 7x = 2 ⇒ x = 2.
∴ Number of boys = 7x = 14
Number of girls = 8x = 16
From (B), Sum of age of all boys.
= 12.2 x 14 = 170.8
Sum of age of all girls = 16 x 11.4 = 182.4
∴ Average age of 30 students = (170.8 + 182.4)/30 = 11.77 years
Hence, statement either (A) are (C) and (B)
are required

of a witness can be considered doubtful
if it is in contradiction with the previous
statement Documents once put into writing
are considered to be the best evidence. The
very object for which writing is used is to
perpetuate the memory of what is written
down, and so to furnish permanent proof of it
Section 62 of the Evidence Act makes it clear
that primary evidence is the document itself. A
"document', as defined in Section 3 of the Act, is any matter which is expressed or described

or remarks or by more than one means and
which can be used for recording the matter.

bamboos swaying due to high wind velocity
and rolling stones that result in sparks setting
off fires in highly inflammable leaf litter on
the forest floor.
