Question

Answer 1

Answer:

216 kg

Step-by-step explanation:

6kg=30 apple

1kg=30/6=5 apple

therefore 1080/5 =216kg

Answer 2

Answer:

216 kg

Explanation:

Assuming that you study in the grades between 6-8. I give the following answer.

This question is related to direct and inverse proportions.

30 apples = 6 kg

1080 apples = y

To find 'y', we have to know what type of proportion it is. In this case, it is direct proportion because as the apples increase, the weight also increase.

So using the direct proportion formula,

$\frac{x1}{y1} = \frac{x2}{y2}$

Where 1 and 2 are sub-scripts.

So we get,

30/6 = 1080/y2

30y2=6480 (by cross-multiplication)

y2=6480÷30

Which is 216.

I want you not to misunderstand y2, x1 and all for exponents. They are not coefficients either. It is actually a subscript.

I did this long explanation instead of the normal way so that you can understand how exactly it is coming out to be 216kg instead of byheart.

Hope it helps. :)))
