Over the centuries, Caveman Colin has carved these original
questions into his stone tablets in a forgotten corner of Dorset,
hoping that someone would come along and try to do them.

1. Jimmy earns £5 per week doing a paper-round in 1998.
If he gets a 10% payrise in 1999, how much does he earn per week, and how much altogether in 1999?
For 2000, he has fewer papers to deliver, so he gets a 10% pay cut; what is his new weekly pay?
2. A family spends £400 each year on a holiday. £50 of this is travelling costs, £80 is
spending money and the rest is accommodation. If the accommodation costs rise by 10% next year
what will their holiday cost altogether?
3. Samantha has a part-time job which pays £24 per week. If she saves 25% in the Building Society
and spends £1.20 a week on drinks after sports, what does she have left for shopping?
What percentage of her total pay is this?
4. Two brothers, Joe and Jack, have part-time jobs. Joe earns £18 every Saturday, Jack has a paper
round, Monday-Friday in term-time only (36 weeks per year) and earns £5 per day. Who earns most in
5. Suppose a man has to earn more than £1600 per year before having to pay income tax.
Calculate his maximum weekly pay if he doesn't pay any tax.
6. I set off from San Diego at 18.30 San Diego time. The 13-hour flight finished at
Heathrow at what time (San Diego time)? If UK time is 8 hours later than San Diego time,
what time did I land at Heathrow? My journey to Dorset took 3 hours, what time did I
7. Which is colder, 5.5 degrees less than 2.5 degrees, or 7 degrees less than 3.2 degrees?
8. Frozen fish must be kept below -25 degrees C. frozen fruit below -15 degrees C.
Jenny's freezer is at -22 degrees C, Fred's is at -11 degrees C.
Which probably lasts longer, Fred's fruit or Jenny's fish?
9. Simplify these where possible:
10. expand then simplify the expression: (x+2)(x-2).
