Tina and Tom were twins. Tina saves and Tom spends. Tom found a $20 note on Sunday evening and spent $2 a day starting on Monday. Coincidentally, Tina started work that Monday and gets $2.50 a day. How long would it be before Tina has more money than Tom?
Paul is on the phone to his friend Pesi. He had this nice pattern that he was trying to describe to Pesi but he couldn’t find the words.
If Paul’s pattern was:
3, 7, 11, 15, …
how could he describe to Pesi how to get any member of the number pattern? How could Paul tell Pesi how to get the 50th number in as simple a way as possible?
Mr Morrison and his daughter Rose both have very bad coughs. They go to the pharmacy and they each get a bottle of QwikQure Cough Medicine. Mr Morrison’s bottle has 300ml and he has to take 10ml every 3 hours. On the other hand, Rose is given a smaller bottle with only 90ml and she has to take 5ml every 6 hours. They have to take the medicine between the hours of 7am and 7pm.
