Answer:

The weight of large box is 13.25 kilograms and the weight of small box is 6.25 kilograms.

Explanation:

Given:

A fruit company delivers its fruit in two types of boxes large and small a delivery of three large boxes and five small boxes that has a total weight of 71 kilograms and a delivery of six large boxes and two small boxes has a total weight of 92 kilograms.

Now, to find the weight of each type of box.

Let the weight of large box be
x.

And let the weight of small box be
y.

A delivery of three large boxes and five small boxes has a total weight of 71 kilograms:


3x+5y=71\ \ \ .....(1)

And, the delivery of six large boxes and two small boxes has a total weight of 92 kilograms:


6x+2y=92\\\\Subtracting\ both\ sides\ by\ 6x:\\\\2y=92-6x\\\\Dividing\ both\ sides \ by\ 2\ we\ get:\\\\y=46-3x\ \ \ \ ......(2)

Now, substituting the value of
y from equation (2) in equation (1):


3x+5y=71\\\\3x+5(46-3x)=71\\\\


3x+230-15x=71\\\\230-12x=71\\\\

Subtracting 230 on both sides we get:


-12x=-159

Dividing both sides by -12 we get:


x=13.25.

The weight of large box = 13.25 kilograms.

Now, substituting the value of
x in equation (1) we get:


3x+5y=71\\\\3(13.25)+5y=71\\\\39.75+5y=71\\\\Subtracting\ both\ sides by\ 39.75\ we\ get:\\\\5y=31.25\\\\Dividing\ both\ sides\ by\ 5\ we\ get:\\\\y=6.25.

The weight of small box = 6.25 kilograms.

Therefore, the weight of large box is 13.25 kilograms and the weight of small box is 6.25 kilograms.
