Question

Please Help! Rohan wants to prepare 6 pillows. If 1 pillow requires 540g of cotton and cost of 100g of cotton is 500. Then find the total cost of 6 pillows and also find the cost of 10, 20 and 15 pillows.
Find the fraction of cotton used for 6 pillows by each pillows.

Answer 1

Heya !!!



Weight of 1 pillow = 540 g


Cost of 100 g cotton = Rs 500


Cost of 1 g cotton = 500/100 = Rs 5



Therefore,


Cost of 1 pillow = 540 × 5 = Rs 2700




Cost of 6 pillows = 6 × Cost of 1 pillow = 6 × 2700 = 16200.



Cost of 10 pillows = 10 × Cost of 1 pillow = 10 × 2700 = Rs 27000.



Cost of 20 pillows = 20 × Cost of 1 pillow = 20 × 2700 = Rs 54000



And,



Cost of 15 pillows = 15 × Cost of 1 pillow = 15 × 2700 = Rs 40500 .

Answer 2

Answer:

Weight of 1 pillow = 540 g

Cost of 100 g cotton = Rs 500

Cost of 1 g cotton = 500/100 = Rs 5

Therefore,

Cost of 1 pillow = 540 × 5 = Rs 2700

Cost of 6 pillows = 6 × Cost of 1 pillow = 6 × 2700 = 16200.

Cost of 10 pillows = 10 × Cost of 1 pillow = 10 × 2700 = Rs 27000.

Cost of 20 pillows = 20 × Cost of 1 pillow = 20 × 2700 = Rs 54000

And,

Cost of 15 pillows = 15 × Cost of 1 pillow = 15 × 2700 = Rs 40500 .
