Show solutionHide solution

Worked solution

Solution:-

Item	Price of each	Number of items	Cost (in ₹)
Bore well for freshwater	₹ 3000	1	1 × 3000 = 3000
Bamboo rack for fish drying	₹ 2000	20	20 × 2000 = 40000
Cement tank	₹ 1000	4	4 × 1000 = 4000
Tray and knife	₹ 300	20	20 × 300 = 6000
Bucket	₹ 75	20	20 × 75 = 1500

Total cost to set up the factory

= 3000 + 40000 + 4000 + 6000 + 1500

= ₹ 54500

In one month, they plan to dry 6000 kg of fresh fish = 1/3 × 6000

= 2000 kg

Q2Written answer

Floramma – let us first calculate for 6 kg of fresh fish.

We buy fresh fish for ₹ 15 per kg.

We sell dried fish for ₹ 70 per kg.

(i) We dry 6 kg fresh fish to get _____ kg dried fish

Show solutionHide solution

Worked solution

Solution:-

We dry 6 kg fresh fish to get 2 kg dried fish.

(ii) For 6 kg fresh fish, we have to pay 6 × __ = ₹ 90

Solution:-

For 6 kg fresh fish, we have to pay 6 × 15 = ₹ 90

(iii) We will sell 2 kg dried fish and get 2 × __ = ₹ __

Solution:-

We will sell 2 kg dried fish and get 2 × 70 = ₹ 140

(iv) So if we dry 6 kg fresh fish, we will earn __ – 90 = ₹ __

Solution:-

So if we dry 6 kg fresh fish, we will earn 140 – 90 = ₹ 50

(v) But if we dry 6000 kg, we can earn ₹ __ × 1000 in one month!

Solution:-

But if we dry 6000 kg, we can earn ₹ 50 × 1000 = ₹ 50000 in one month.

Q3Written answer

Jhansi — I found that for 6000 kg fish, we would need 1500 kg salt every month! Its price is Rs ₹ per kg.

Monthly costs:

a) Salt 1500 × 2 = ₹ ____

b) Packing and bus charges = Rs 3000

So the total monthly cost of drying and selling the fish = ₹ ____

Fazila — That sounds very good! Our calculations tell us that every month our Bank will earn Rs 44,000!

Show solutionHide solution

Worked solution

Solution:-

(a) Salt 1500 × 2 = ₹ 3000

Then,

The total monthly cost of drying and selling the fish = ₹ 3000 + 3000

= ₹ 6000

Hence, earning = 50000 – 6000

= ₹ 44000
