Question

The 3 kg potatoes costs 20 rupees find
of 750g of potatoes​

Answer 1

As per data given in the question,

We have to find  the cost of 750g of potatoes​ if the cost of 3 kg potatoes costs 20 rupees.

From the data,

We have,

Cost of 3 kg potatoes costs 20 rupees.

So, cost of 1 kg potatoes will be $\frac{20}{3}$ Rs.

As we know that,

1 Kg = 1000 gram

So, cost of 1000 g potatoes =  $\frac{20}{3}$ Rs.

So, cost of 750 grams potatoes will be,

$[ \frac{20}{3} \div 1000 ]\times 750\\=Rs.\:5$

Hence, cost of 750 g potatoes will be Rs. 5.

Answer 2

Answer:

Step-by-step explanation:

As we know that,

1 kg = 1000 g

so ,

3 kg = 3000 g

Given  3 kg = 20 rupees

3 kg = 3000 g = 20 rupees

As, 3000 g = 20 rupees

1 g =  $\frac{20}{3000}$

1 g = 0.066 rupees

So ,

to get the 750 g of rate we have to multiply 1 g of rate by 750

750 g = 0.0066 * 750  

750 g = 4.95 rupees

The 3 kg potatoes costs 20 rupees. The cost

of 750g of potatoes​ is 4.95 rupees
