SOLUTION :-

Let us take the cost price of 1 kg of potatoes as ''y ''

We also , don't know  the cost price of 20 kg's of potatoes, so let this be as  ⇒ 20 × y

We also don't know the profit which was earned by vegetable seller when he sold 20 kg's of potatoes , so let this be as :- 5 × y

Now ,let us apply the profit % formula :-

Profit % = Profit / Cost price × 100 %

= 5 y / 20 y × 100 %

= 1 /4 × 100 %

= 25 %

Hence the profit percentage , he earns after selling the potatoes for 20 kg's is 25%
