$\frac{2}{3} \times 30 = 2 \times 10 = 20 \\ \\ Geeta\ worked\ out\ 20\ problems\ of\ them. \\ \\ 30 - 20 = \bold{10}\ problems\ were\ still\ left\ to\ be\ worked\ out\ by\ her. \\ \\ \therefore\ \bold{10}\ is\ the\ answer.$

$\\ \\ OR \\ \\ Geetha\ worked\ out\ \frac{2}{3}\ of\ the\ problems. \\ \\ 1 - \frac{2}{3} = \frac{1}{3}\ of\ the\ problems\ were\ still\ left\ to\ be\ worked\ out\ by\ her. \\ \\ That\ is,\ \frac{1}{3} \times 30 = 1 \times 10 = \bold{10}\ problems\ were\ still\ left\ to\ be\ worked \\ out\ by\ her. \\ \\ \therefore\ \bold{10}\ is\ the\ answer. \\ \\ \\ Thank\ you. \\ \\ \\ \#adithyasajeevan$
