When completing an online shopping transaction, a typical shopper takes 12 seconds to select each product and another 15 seconds to complete the check-out process. If it takes
39 seconds to complete a transaction, how many products are being purchased?

In 26 seconds to complete a transaction, 2 products are being purchased.

Step-by-step explanation:

Here, time taken to select 1 item  = 9 seconds

Time taken in all to check out = 8 seconds

Here, time taken to shop = 26 seconds

Now as check out process takes 8 seconds , so the

Time left to ACTUALLY SHOP =  Total Time  - Time Used to check out

                                                  = 26 seconds = 8 seconds = 18 seconds

Shopping of 1 item = 8 seconds

Shopping of 2 items  = 2 x ( Time taken in 1 item) = 2 x  9 = 18 seconds

So, in 18 seconds, 2 clothing item can be selected.

Hence,in 26 seconds to complete a transaction, 2 products are being purchased.
