Answer 1

9..let,there are n no of marbles
so B have the (1/2×1/3)=1/6marbles of total=n/6
and C has the (1/2×2/3)=2/6 marbles of total=2n/6

now,c has twice that of b
it is applicable for any no

so this is option c.. it has no unique solution

10. 2+
$\sqrt{x}$
=9

or,
$\sqrt{x}$
=7
or,x=49.... option d

11. 6x-9=-6x-4
or,12x=5
or,x=5/12.. option d
