Question

If the cost of 1KG grapes is 280.then what cost of 250g of grapes

Answer 1

Step-by-step explanation:

First convert 40 grams to kg. A kilogram is 1000 grams, so you divide 40 by 1000 which is .04 kg.

40 grams * 1 kg / 1000 grams = .04 kg

(Note here that 1 kg = 1000 grams meaning that 1 kg / 1000 grams = 1; anything divided by itself is one; therefore, when I multiply by 1 kg / 1000 grams I’m not changing the value, only the units.)

Then you simply multiply the price per kg by the number of kg giving 6.6.

.04 kg * 165 / 1 kg = 6.6

Answer 2

1kg = 1000g

Cost of 1000g grapes = ₹280

Cost of 1g grapes = ₹280/1000

Cost of 250g grapes = ₹ 280×250/1000 = ₹70 (Ans.)
