Here are the solutions to the mathematics questions:
4. If X is a positive integer, find all possible values of X given that 1≪X<7. (3 marks)
Step 1: Interpret the inequality.
The notation 1≪X is typically used to mean "1 is much less than X". However, in the context of finding integer values for X, it is most commonly interpreted as 1<X.
So, we are looking for positive integers X such that 1<X<7.
Step 2: List the integers that satisfy the condition.
The integers strictly greater than 1 are $2, 3, 4, 5, 6, 7
