A fruit company delivers its fruit in two types of boxes: large and small. A delivery of eight large boxes and four small boxes
vazorg [7]

Answer:

Weight of Large Box = 18.5 kg

Weight of Large Box = 13.25 kg

Step-by-step explanation:

<u>Given:</u>

There are two types of boxes i.e. Large and Small

Let the weight of Large boxes = L kg

Let the weight of Small boxes = S kg

As per given statement:

  • A delivery of eight large boxes and four small boxes has a total weight of two hundred and one kilograms.

Writing equation for above:

8L + 4S = 201 ....... (1)

  • A delivery of three large boxes and two small boxes has a total weight of eighty two kilograms.

Writing equation for above:

3L + 2S = 82 ....... (2)

Now, by solving the equations (1) and (2), we can get the values of L and S.

<em>Multiplying equation (2) with 2 and subtracting from equation (1):</em>

8L + 4S = 201

-

2 \times (3L + 2S) = 82 \times 2

8L + 4S = 201

-

6L + 4S = 164

--------------------

2L = 37

L = 18.5 Kg

Putting value of L in equation (1):

8 \times 18.5 + 4S = 201\\\Rightarrow 148 + 4S = 201\\\Rightarrow  4S = 201 - 148\\\Rightarrow  4S = 53\\\Rightarrow S = 13.25\ kg

So, the answer is:

Weight of Large Box = 18.5 kg

Weight of Large Box = 13.25 kg
