Question

How many glasses of capacity each, canbe filled from a 21 bottle of cold drink? class 6

Answer 1

Hey
Let the number of glasses be x.
Therefore total volume filles by all glasses =
$\frac{x}{4}$
This is now representing the volume of bottle,
therefore
$\frac{x}{4} \times 2 = number \: of \: glasses \\ hence \: number \: of \: glasses = x = 2 \times 4 \\ x = 8 \: answer$
