Question

В магазине на 3 полках стояло 140 пакетов сока . Когда с одной полки взяли 16 пакетов а с другой 4 пакетов то на всех трех полках осталось пакетов поровну .По сколько пакетов осталось на каждой полке?

Answer 1

х - на первой

y - на второй

z - на третьей

 

x - 16 = у - 4 = z  

 

x+y+z=140  значит х + y +( x - 16) = 140

но если х - 16=у -4, то  у = х - 12, значит

 

х + х - 12 + х - 16 = 140

3х - 28 = 140

х = 56

у = 44

z = 40

 

Answer 2

Solution:

Let's solve this step by step.

1. Total Number of Juice Packets: - Initially, there were 140 juice packets on 3 shelves.

2. Packets Taken from Shelves: - 16 packets were taken from one shelf, and 4 packets were taken from another shelf.

3. Remaining Packets on Each Shelf: - After the packets were taken, an equal number of packets were left on each shelf.

Calculation:

1. Total packets = 140 2. Packets taken = 16 + 4 = 20 3. Remaining packets = 140 - 20 = 120 4. Equal packets on each shelf = 120 / 3 = 40

So, 40 packets were left on each shelf.
