Question

Aruna buys 12000 kg of fresh fish at Rs. 40 a kg .She dries it . The dried fish is 1/3rd of the fresh fish. She sells the dried fish at Rs. 200 and pays Rs. 890 for transportation. How much does she earn in this whole transaction

Answer 1

cost of 1 kg fish is 40 rs

so cost for 12000 kg fish = 12000 × 40

= 480000 rs

now after drying 1/3 rd of total fish remains

i.e. 1/3 × 12000

= 4000 kg of fish remains

selling price of fish is 200 rs per kg

so total selling price is = 200 × 4000

= 800000

so profit = 800000 - 480000

= 320000 rs

also she gives 890 rs for transportation

so actual profit is

320000 - 890

= 319110 rs
