1. Remainder Concepts
Mr Tan had a sum of money. He donated $1400 to a charity and spent $400 on some Christmas presents. He then gave 2/5 of the remainder to his 3 children. Given that each child received 1/12 of Mr Tan's original sum of money, how much did each child receive?

2. Repeated Identity Concept
Andy, Beckham, Chris and Daniel shared $168. Daniel received 1/7 of the total amount of money received by Andy, Beckham and Chris. Andy received 3/4 of the total amount of money received by Beckham and Chris. Beckham received 2/5 as much money as Chris. How much did Berkham receive?

3. Equal Concept
A box contained some pencils and pens. 20% of the pencils and 3/5 of the pens were removed. In the end, there were half as many pencils as pens. Given that there were 30 more pens than pencils at first, find the number of pencils in the box at first.

4. External Transfer With Unchanged Quantity Concept
In November, Mrs Tan spent 80% of her monthly salary. In December, her monthly salary increased by $900 and he saved 15% of her new monthly salary. Given that she saved the same amount of money in these two months, what was her monthly salary in December?

5. Internal Transfer With Unchanged Total Concept
John. Matt and Luke put in their money together to buy a toy. John paid 1/3 of the total amount paid by Matt and Luke. Matt paid 1/5 of the total amount paid by John and Luke. If Luke paid $60 more than Matt, how much did the toy cost?
