Am I being picky or...

They have rounded it up a bit? Anya, I am shocked that anyone does the maths for all that shops claim ( and a bit impressed as well!) It's as much as I can do this week to remember to actually buy them.

My maths is very ropey, but....

Done it the other way to check &

1440 x 31.3 = £4.4572

1440 x 32 = £4.6080

so does that somehow makes 31.3p per sheet nearer?

No, they haven't rounded it up Roses they have claimed it is 31.3p per 100 sheet when in fact it's 32p per 100 sheets.

(Left out the 100 sheets bit in the OP)

1440 X 31.3 = 45072

Sorry, I should have said rounded it down, they probably think it sounds more sciencey that way.

Or it could be a genuine mistake ( yer never know!)

But 1440 x 32p = £4.6080

1440 x 31.3p + £4.50072

So Sainsbury's is right. I think...

Enjoy!

Sorry, took me so long to work that out that several posts have now made it clear!

Or have they...?

Oh sheet! Sainsbury's hadn't reckoned on a Gransnet Gran !

Your maths is dodgy, anya but so is theirs.
You have the sum the wrong way round.
If you divide the £4.50 by 1440, you get 3.125 pence per sheet, the right answer.
They have done rounded it up and put the decimal point in the wrong place

You divided 1440 by 4.5 to get 320 - and then put in the decimal point in the wrong place.

And they told us it would all be so much simpler with decimalisation!

Ana I have been doing division sums on a calculator and then multiplying them back again to check.

oK it's

4.5 / 1440 = 31.25

"Left out the 100 sheets bit in the OP"

!!!

How do you expect us to work it out if you leave bits out?!

It's bad enough as it is!

If it really were 31.3 or 32 pence a sheet, that would be more than a pound a shit!

And I'm not doing it.

So there.

Rude.

Your maths is still dodgy, Anya £4.5 / 1440 = 3.125 pence

X posts Elegran

Love the thought of everyine dashing to the calculator apps on their devices and screwing up their faces when faced with decimal points.

Yes, I'm always guilty of that Elegran

Wonder if there really is 160 shits sheets on each roll...... think lol go and count them now
