Confused with a practice question (picture included)

I hope the above image works! Basically I'm working on Costs and Revenues and attempting the above question from the Osborne tutorial book. You can see my original calculations crossed out, and the given answers written in.
I'm sure there's just something obvious I'm missing and the penny will drop eventually; but all we've been taught so far is to calculate basic pay INCLUDING overtime hours, and then calculate just the added premium of the overtime (for example, equivalent to half of basic pay).
The way it's written in the image, though, it says 512 hours were worked, but it's only worked out basic rate for 464 of those hours. Then it's calculated just the premium for the overtime hours  so surely the 48 (30+18) hours of overtime haven't been fully calculated? Haven't they missed the basic rate calculation for these hours?
Any help appreciated!

Overtime hours are included in the 464 according to the brackets. I think the 512 is a red herring that shouldn't really be there.0

It would actually make much more sense if the 512 hours was the incorrect part  although they've made the exact same (possible) error in the workbook, too.0

Certainly odd, but that's how they've calculated the answer.0

I agree with CeeJay Six
the Basic pay hours includes the overtime. The 512 should really not be there and should be greyed out. The question would make more sense then

The 512 is absolutely correct. This is used only to calculate a payment, the total/ actual hour worked is 416 hours.
The 464 already included OP rate 1 and 2 hence the actual hours pay is 416 which is £4160 on a basic pay. OP rate 1 and 2 is 48 hours altogether.
464  48 (OP rate 1 and 2) = 416, SO 416 *£10 = £4160 ( BASIC RATE PAY WITHOUT OVERTIME PREMIUM)
OVERTIME RATE 1 is 30*12.50 ( BASIC RATE and a QUARTER)= £375
OVERTIME RATE 2 is 18 * £15 (BASIC RATE and a HALF) = £645
So TOTAL PAY IS £4160 + £375 + £645 = £4805
But because the BASIC RATE of overtime worked is included in the BASIC PAY then we will have 416 (BASIC HOUR WORKED) + 48 ( BASIC HOUR OVERTIME ) = 464
464* 10 = £4640
30*£2.50 (OVERTIME PREMIUM ie a QUARTER OF BASIC PAY WITHOUT BASIC PAY) = 75
18* £5 ( OVERTIME PREMIUM ie HALF OF BASIC PAY WITHOUT BASIC PAY) = £90
SO, £4640 + £75 + £90 = £4805
Hope someone finds this useful.0
