P5P6 Math: Before and After (2 Equal Total at first with 2 different item types)

This question type is the slightly more complex version of the one shown here.

Both person start with the same total.

Each will use some of their total to make different quantities of 2 items.

The comparison between each of the 2 items and their respective remaining are given.

"Comparison models" will be needed to solve such questions.

Alan and Ben has equal amount of clay.

After Alan used his clay to make 10 bowls, he has 1.2kg of clay left.

After Ben used his clay to make 16 plates, he has 0.66kg of clay left.

P3/P4 Before and After One Party Unchanged (Start Same, End Multiples)

In such questions, 2 values are being presented to be equal at first.

One of the values undergo a change (add/subtract) and it results with the larger value becoming a multiple of the smaller value at the end.

Before and After questions are staples for P3 and P4 students as they would need to know how to visualize these questions using "Before and After Comparison Models".

Such questions are common in Section C of P3 and P4 exam papers.

Harold and Kumar has the same number of sweets at first.

After Harold ate 45 sweets, 

Kumar now has 4 times as many sweets as Harold.

How many sweets did both have altogether at first?

P4P5 Math: Before and After Start Same End Multiples

One of the "Before and After" problem sums where the 2 parties start with equal value.
After each undergo a decrease, one of value remaining is a multiple of the other.

Such questions are common in P4 and P5 exams.

They either appear in Paper 1 of P5 or Section C of P4 papers.

Calculator usage is not allowed.

Evelyn and Kathy each have the same number of stamps at first.

After Evelyn sold 24 stamps and Kathy gave away 100 stamps,

Evelyn now has thrice as many stamps remaining as Kathy.

P4/P5 Math: Before and After Fractional Decrease (Start Same, End with Difference)

The questions starts off with equal quantities of 2 different items.

Each item undergoes different fractional decrease.

The difference at the end is given.

Such question requires students to be able to use "Before and After" models 

and use the denominator of each fraction to show the total items of either type at first. 

Such questions usually appear in P4 SA2 papers and P5 Paper 1.

Calculator usage is not allowed.

A slightly more complex version of this question for P5 and P6 students can be found here.

Alison has the same number of red and white roses.

After giving away ¹/₄ of the red roses and ¹/₃ of the white roses,
