bob works 32 hours a week and gets paid £12.50 per hour. 20% of his pay is income tax. he also pays national insurance, and so is left with £280 after tax.

how much does he pay for national insurance? how much is this of his salary before tax?

Bob pays £48 for national insurance, which is 17.14% of his salary before tax.
gross pay = 32*12.50 = £ 400
net pay = 80% of 400 = £ 320

insurance + 280 = 320
insurance = £ 40

rate = 40/400 = 10%
