It is 20 white marbles

step by step explanation:

Fraction of the yellow marbles:

$1 - \frac{1}{4} - \frac{3}{8} = \frac{3}{8}$

let total number of marbles be x :

${ \sf{ \frac{3}{8} \: of \: x = 30 \: yellow \: marbles}} \\ \\ \frac{3}{8} \times x = 30 \\ \\ 3x = 30 \times 8 \\ 3x = 240 \\ x = 80$

Total marbles = 80 marbles

for white marbles:

$= \frac{1}{4} \times 80 \\ \\ = 20$
