These seven original questions mix the skills from the Home Science lessons. Try each one on paper first, then open the answer and compare your method, not only your final figure.

Questions
Q1. A 1 kg bag of flour costs RM4.50 and a 2.5 kg bag costs RM10.00. Find the price per kilogram of each bag.
Answer
1 kg bag: RM4.50 per kg. 2.5 kg bag: RM10.00 ÷ 2.5 = RM4.00 per kg.
The larger bag is RM0.50 cheaper per kilogram.
Q2. A family makes 12 cupcakes from one recipe. They need 40 cupcakes for a school sale. How many recipes must they make, and why?
Answer
40 ÷ 12 = 3.33. Three recipes make only 36 cupcakes, which is 4 short, so they must make 4 recipes. That gives 48 cupcakes, with 8 spare.
Q3. A household has RM120 for groceries this week and has already spent RM47.80. How much is left, and is it enough for a RM35.50 fish purchase and a RM18.90 vegetable purchase?
Answer
Left: RM120.00 − RM47.80 = RM72.20. The two purchases cost RM35.50 + RM18.90 = RM54.40. Since RM54.40 is less than RM72.20, it is enough, with RM72.20 − RM54.40 = RM17.80 remaining.
Q4. Explain why raw vegetables should be washed before they are cut.
Answer
Model answer: “Raw vegetables should be washed first, because soil and germs on the surface can move onto the knife and board during cutting. The cut surface then carries them into the food, so washing before cutting removes most of them before they spread.”
Q5. A student writes “Keep the fridge cold” as a step for storing milk. Rewrite it as an explained step.
Answer
“Milk should be kept in a cold refrigerator, because bacteria multiply more slowly at low temperatures, so the milk stays fresh for longer.”
Q6. Two options for a school bag.
Bag A costs RM45 and lasts about 2 years. Bag B costs RM28 and lasts about 1 year. Which is better value for a 2-year period? Justify your choice.
Answer
Bag A: RM45 for 2 years, RM22.50 a year. Bag B: two bags over 2 years cost 2 × RM28 = RM56, which is RM28 a year.
Choose Bag A. It costs RM11 less over two years. The condition is that the lifespan claim holds; if Bag A tore in its first year, Bag B could be the better value.
Q7. Rewrite this reflection to make it specific: “I learned a lot about budgeting and will do better next time.” Invent two details.
Answer
Your details will differ. A strong version: “I planned a RM60 menu but the fish cost RM8 more than I had listed, so I swapped it for eggs and stayed within RM60. Next time I will check prices on the day before writing the final budget.”
It names a cost, a cause and a change.
If you got these wrong
- Unit prices and planning sums (Q1 to Q3, Q6): go to justify a household resource decision with evidence and interpret quantities in a planning task.
- Explanations (Q4, Q5): read explain a process, not just list steps.
- Reflection (Q7): read write your own project reflection.
