Sheela ate 3/5 th of a cake .she gave 1/5th of the remaining cake to a friend . what Portion of the cake is still left with her

Answer 1

Let the sheela had x cake
Sheela ate 3/5 of cake
$= \frac{3}{5} x$


Then,
Sheela gave 1/5 of the remaining cake to her freind
$= \frac{1}{5} \times \frac{3}{5} \times x \\ = \frac{3}{25} x$

Portion of cake that sheela left
$= x - \frac{3}{25} x \\ = \frac{25}{25} x - \frac{3}{25} x \\ = \frac{22}{25} x$


$sheela \: left \: \frac{23}{25} \: portion \: of \: cake$
