Math question

[kittykat]

Hi all,

My daughter has a standard grade exam tomorrow and is doing revision, but a question has stumped her, as they have not done percentages like this,only like 6.5 or 25 % and i am absolutely hopeless at anything like this and was wondering if anyone would be able to show her how to work it out, she may not even get a question like this but its just in case.......thankyou in advance xx


Sally invests £4200 in the platinum Saver Account which pays 6.3% interest per annum.

How much simple interest will she recieve after 10 months.

[Jaco45er]

6.3% & per £100 per annum is £6.30. Divide that by 12 you get 0.52p (rounded down).

0.52 x 10 = £5.20 for 10 months interest.

So, at £5.25 per £100, a £1000 would be £52.50.

£4000 @ (£52.50 per £1000) = £210.00

Plus

£200 @ (£5.25 per £100) = £10.50

£210 + £10.50 = £220.50

I think

0.52 x 10 = £5.20 for 10 months interest.

So, at £5.25 per £100, a £1000 would be £52.50.

£4000 @ (£52.50 per £1000) = £210.00

Plus

£200 @ (£5.25 per £100) = £10.50

£210 + £10.50 = £220.50

Smart azz Lol

Ha Ha this is like countdown, my daughter managed to work it out a different way but you were right jaco we'll soon be able to start no more panic countdown.

£4200 6.3%

4200 divided by 100 = 42

42 x 6.3 = 264.6

264.6 divided by 12 = 22.05 x 10 = £220.50 yay


thanks guys
