I got the ans that A is greater but it differs from the soln in the official book where have I gone wrong?

I solved and got the ans as D but its not the correct ans

Here lengths is equal to breadth and length right or only length?

c/40 vs 1.2 (c/50)

Compare these two, where c is the constant that’s the product of pressure and volume.

You computed the slope incorrectly the first time. It should be 2 - 5, not 2 - (-5).

Length is just a pair of opposite sides of the rectangle. The exact wording isn’t as important.

For Quantity B

My interpretation was incorrect as I considered

1.2

*V*50=C

I thought 1.2 times volume means 1.2*V

@Leaderboard

You are trying to compare the volumes. This means that the variables you are trying to compare should not have V in it. See my earlier answer.
