In a former "Assumption Method" example shown here, the element of "deduction" is introduced and students will have to use a slightly different way to address the "deductions" when performing calculations using the "Assumption" method.
This question type below, requires students to be able to handle another variable and remove it from the total number of marks before using the "Assumption" method(with subtraction).
Such questions are now common in P5 SA2 Paper 2.
Calculator usage is allowed.
