Question

While doing a waste audit of his kitchen, Rohan collected 168 plastic packets in 4 months. How many packets will he collect over 8 months?​

Answer 1

Answer:

336 plastic collected in 8 months

Step-by-step explanation:

plastic collected in 4 months = 168

plastic collected in 1 month = 168/4

                                              = 42

plastic collected in 8 months = 42x8

                                                = 336 plastic

Answer 2

Answer:

Rohan will collect 336 packets in 8 months.

Step-by-step explanation:

Given:

Rohan collected 168 plastic packets in 4 months.

Let number of plastic packets collected in 8 months be X

                        no,of plastic packets         no.of months

                                    168                                    4

                                      X                                      8

Since NO. of plastic packets and no.of months are directly proportional

So,

168 : X : : 4 : 8

According to proportionality rule,

Product of mean =Product of extreme

   X × 4 = 168 × 8

    4X =1344

       X= 1344/ 4

       X=336

No.of plastic packets collected= X = 336
