Answer:

$\frac{1}{7}$

Step-by-step explanation:

Amount of cake Rani ate = $\frac{2}{7}$

You need to understand that her brother ate 4/5 of the remaining part, not of the entire cake, so we need to figure out the actual amount out of the entire cake first before calculating how much is left.

Amount of cake brother ate = $\frac{4}{5}$ × ( $\frac{7}{7}$ - $\frac{2}{7}$ )

= $\frac{4}{5}$ × $\frac{5}{7}$

= $\frac{4}{7}$

Amount of cake left = $\frac{7}{7}$ - $\frac{2}{7}$ - $\frac{4}{7}$

= $\frac{1}{7}$
