Hi all,

me and my brother are having a discussion and ive got to the stage where im so confused i dont know which answer is right.

for example... (forget roundings)

He is saying..

182.82 - VAT at 17.5% = £150.83 on a calculator

150.83 + VAT at 17.5% = £177.21 on a calculator

Im saying..

£182.82 - VAT at 17.5% = £155.59

£155.59 + VAT at 17.5% = £182.82

Now ive given his a go on the calculator by putting in '182.82 - 17.5%' and it does equal the £150.83 so can someone give it a few minutes and work out the right suggestion, its doing my head in!!!

4,071The maths is 150.83 * 1.175

182.82 minus VAT is 182.82 / 1.175 = £155.59

You cannot take the gross and minus 17.5% because the gross is 117.5%. The VAT is 17.5% of the Net, which is 100%.

If you are trying to find the VAT from the gross, do not use percentages, use 1.175 or the VAT fraction of 7/47

Obviously VAT is now 20%....

45460Nice way my tutor once put it is like a Mark up.

Gross - 117.5% 182.82/117.5 = 1.555915

VAT -17.5% 1.555915* 17.5 =27.22851

Net-100% 182.82-27.22851= 155.5915 or 1.55915*100

They way your brother is calc'ing is on a Margin basis.

i.e

Gross =100% 182.82/100 to give 1% =1.8282

VAT =17.5% 1.8282 *17.5 = 31.9935

Net =82.5% 182.82-31.9935=150.8265 or 1.8282*82.5

585This reminds me of a puzzle

3 friends go to a pub.

They all put in £10 each in a pot and a give it to a bar man to look after it.

at the end of outing, the total of bill came at £25

The bar man knew his customers. So that none of the friends (typical accountants) do not feen that their contribution to the pot was unfair, the bar man gave back £3 so that each friend will get back £1 each. He retained £2 as a tip.

Reconciliation

Cost to each friend ( £10 - £1) = £ 9 time 3 = £27

£27 plus £2 retained by barman as a tip = £29

But the bar man was given £30 to start with!

where has the £1 gone?

654Total bar bill = £25 plus £2 tip = £27

Each friend pays £9 x 3 = £27

The barman was given £30, less £3 = £27
