Given:

Weight of fish = 9000 kg

S.P. of fresh fish = Rs. 30/kg

S.P. of dried fish = Rs. 120 /kg

When fresh fish dried it remain \(1 \over 3\) of its weight.

Formula:

Price of fish = Weight × Rate

Calculation:

Price on selling fresh fish = 9000 × 30

Price on selling fresh fish = 270000

Weight of dried fish = \({1 \over 3} × 9000\) = 3000

Price on selling dried fish = 3000 × 120

Price on selling dried fish = 360000

Difference of selling price = Selling price of dried fish - Selling price of fresh fish

Difference = 360000 - 270000

Difference = Rs. 90000

∴ If flora sells dried fish, she will get Rs. 90000 more than if she sells fresh fish.
