a = b + 8kg
c = 3b
a + b + c = (b + 8) + b + (3b) = 5b + 8kg = 98kg
5b = 98kg - 8kg = 90kg
b = 18kg
c = 3b = 18kg * 3 = 54kg
**a = albert, b = boon heng, c = cui hua**

For Q3, draw a model to represent the two numbers. Show your working and we'll give you feedback on your work. Same for Q4, you can draw a model first and then see what the next steps are.
