Question

the cost of 16 packets of an article each weighing 900 grams is Rs 84.what will be the cost of 27 packets of the article each weighing 1 kg

Answer 1

Cost of one 1 kg packet = ((1000/900) x 84)/16
= Rs. 5.83
Cost of 27 packets = Rs. 5.83 x 27 = Rs. 157.5

Answer 2

Answer:

Rs.157.5

Step-by-step explanation:

1000 grams = 1 kg

900 grams =$\frac{900}{1000}$

Now we are given that the cost of 16 packets of an article each weighing 900 grams is Rs 84.

So, Cost of one 1 kg packet = $\frac{\frac{1000}{900} \times 84}{16}$

                                              = $5.83$

Cost of 27 packets = Rs. 5.83 x 27 = Rs. 157.5

Thus the cost of 27 packets of the article each weighing 1 kg is Rs.157.5
