Our girls were given difficult and very difficult problems to solve in 90 minutes! No calculators were allowed, only plain paper and a pencil.
Here are two questions for you to try:
1. Which of the following cannot be written as the sum of two prime numbers?
A =5, B =7, C =9, D =10 or E =11
2. Given that
x+y+z = 1
x + y – z = 2 and
x – y – z = 3
what is the value of xyz?
A = -2, B = -1/2, C = 0, D = 1/2 or E = 2
The students’ solutions have been sent to Leeds University for marking and we now await the results. Well done to the students who took part in this event.
