The cost of 3 and 1/4 kg of potatoes will be 130 rupees.

Given:

the cost of 1 kg of potatoes is = 40 rupees

To Find:

the cost of 3 and 1/4 kg of potatoes

Solution:

we know that 1 kg = 1000 g

⇒ 1/4 kg = 1000/4 = 250 g

also 3 kg = 1000 × 3 = 3000 g

so, 3 and 1/4 kg = 3000 + 250 = 3250 g

now, we are given that 1000 g of potatoes cost 40 rupees

⇒ cost of 1 g of potatoes = 40/1000 rupees

so, the cost of 3250 g of potatoes will be = 3250 × 40/1000

= 130

Thus, the cost of 3 and 1/4 kg of potatoes will be 130 rupees.
