Question

Jhansi ― I found that for 6000 kg fish we would need 1500 kg salt every month! Its price is Rs 2 per kg.
Monthly costs:
(a) Salt 1500 × 2 = Rs ______
(b) Packing and bus charges = Rs 3000
So the total monthly cost of drying and selling the fish = Rs ______
Fazila ― That sounds very good! Our calculations tell us that every month our Bank will earn Rs 44,000!

Answer 1

(a) Monthly cost of salt = 1500 × 2 = Rs 3,000

(b) Cost of 1 kg of fresh fish = Rs 15
Cost of 6000 kg of fresh fish = Rs 15 × 6000
= Rs 90,000

Total cost = Cost of fresh fish + Cost of packaging and bus charges + Cost of salt
= Rs 90000 + Rs 3000 + Rs 3000
= Rs 96,000

Now, weight of dried fish is one-third of the weight of fresh fish.
So, weight of dried fish = 6000 kg ÷ 3
= 2000 kg

Selling price of dried fish = Rs 70
Money earned by selling 2000 kg of fish = Rs 70 × 2000
= Rs 1,40,000

Cost of drying and selling the fish = Money earned by selling the fish - Total cost
= Rs 140000 − Rs 96000
= Rs 44,000
