八道购物问题,练习折扣、回扣、礼券与组合优惠。
第 1 题
一个护具套装原价 RM280,折扣 25%。折扣后需付多少?
剩余百分比 = peratus baki
Soalan meminta harga selepas diskaun 25%. Tukar diskaun kepada peratus yang masih perlu dibayar, kemudian darab dengan harga asal. Gunakan anggaran untuk memastikan jawapan kurang daripada harga asal tetapi bukan terlalu kecil.
Contoh: Diskaun 20% meninggalkan 80%; RM120 × 80% = RM96.
Awas: 25% ialah amaun yang ditolak, bukan amaun yang dibayar.
剩余百分比 = remaining percentage
The question asks for the price after a 25% discount. Convert the discount into the percentage still payable, then multiply by the original price. Estimate first to make sure the answer is below the original price but not unreasonably small.
Example: A 20% discount leaves 80%; RM120 × 80% = RM96.
Watch out: 25% is the amount removed, not the amount paid.
第 2 题
一笔 RM450 的付款可获得 4% 现金回扣。回扣是多少?
回扣额 = amaun rebat
Soalan hanya meminta jumlah rebat, bukan perbelanjaan bersih. Darab amaun bayaran dengan kadar rebat dan berhenti selepas mendapat wang yang dipulangkan. Semak bahawa rebat kecil berbanding bayaran asal.
Contoh: Rebat 6% daripada RM250 ialah RM250 × 0.06 = RM15.
Awas: Jangan tolak rebat daripada bayaran kerana soalan tidak meminta perbelanjaan bersih.
回扣额 = rebate amount
The question asks only for the rebate amount, not net spending. Multiply the payment by the rebate rate and stop when you have found the money returned. Check that a small percentage gives an amount much smaller than the original payment.
Example: A 6% rebate on RM250 is RM250 × 0.06 = RM15.
Watch out: Do not subtract the rebate because net spending is not requested.
第 3 题
一件商品原价 RM600,先折扣 15%,再使用 RM40 礼券。实际付款是多少?
先折扣后礼券 = diskaun sebelum baucar
Soalan mempunyai dua potongan yang berlainan. Kira harga selepas diskaun daripada harga asal, kemudian tolak nilai baucar daripada harga baharu itu. Baucar ialah amaun tetap, jadi jangan menukarnya kepada peratus.
Contoh: RM300 × 90% = RM270, kemudian RM270 − RM20 = RM250.
Awas: Jangan tolak baucar daripada harga asal sebelum mengira diskaun.
先折扣后礼券 = discount before voucher
The question has two different reductions. Calculate the discounted price from the original price, then subtract the voucher value from that new amount. A voucher is a fixed amount, so do not convert it into a percentage.
Example: RM300 × 90% = RM270, then RM270 − RM20 = RM250.
Watch out: Do not subtract the voucher from the original price before finding the discount.
第 4 题
一件商品原价 RM800,先折扣 10%,再使用 RM50 礼券,实际付款可获得 5% 现金回扣。净支出是多少令吉?请输入答案。
净支出顺序 = urutan perbelanjaan bersih
Soalan meminta satu jawapan selepas diskaun, baucar dan rebat. Cari harga selepas diskaun, tolak baucar untuk mendapatkan bayaran sebenar, kira rebat daripada bayaran itu, kemudian tolak rebat. Simpan dua tempat perpuluhan untuk wang.
Contoh: RM400 × 80% = RM320; RM320 − RM20 = RM300; rebat 10% = RM30; bersih RM270.
Awas: Rebat dikira daripada bayaran selepas baucar.
净支出顺序 = net-spending order
The question asks for one result after a discount, voucher, and rebate. Find the discounted price, subtract the voucher to get the actual payment, calculate the rebate from that payment, then subtract it. Keep two decimal places for money.
Example: RM400 × 80% = RM320; RM320 − RM20 = RM300; a 10% rebate is RM30; net spending is RM270.
Watch out: Calculate the rebate from the payment after the voucher.
第 5 题
购物满 RM500 可获回扣 RM50。诗蒂消费了 RM680,净支出是多少?
固定金额回扣 = Rebat jumlah tetap
Rebat ini ialah jumlah tetap RM50, bukan peratus. Semak dahulu sama ada belanja RM680 mencapai syarat RM500. Jika ya, tolak RM50 daripada jumlah yang dibelanjakan.
Contoh: Contoh: belanja melebihi RM300 dapat rebat RM20. Belanja RM350, perbelanjaan bersih = 350 − 20 = RM330.
Awas: Jangan tukar rebat tetap kepada peratus dan jangan tolak daripada RM500. Rebat ditolak daripada jumlah sebenar yang dibelanjakan.
固定金额回扣 = Fixed-amount rebate
This rebate is a fixed RM50, not a percentage. First check whether the RM680 spent reaches the RM500 condition. If it does, subtract RM50 from the actual amount spent.
Example: Example: spend RM300 or more to get a RM20 rebate. Spend RM350, net spending = 350 − 20 = RM330.
Watch out: Do not turn a fixed rebate into a percentage, and do not subtract it from RM500. Subtract it from the actual amount spent.
第 6 题
超市优惠:每消费满 RM200 回扣 RM10。顾客消费 RM730,可获回扣多少?
每满额回扣 = Rebat bagi setiap jumlah penuh
Rebat RM10 diberi untuk setiap RM200 yang penuh sahaja. Bahagikan RM730 dengan RM200 dan ambil nombor bulat sahaja, kemudian darab dengan RM10.
Contoh: Contoh: setiap RM100 penuh dapat rebat RM5. Belanja RM460 mengandungi 4 kali RM100 penuh, jadi rebat = 4 × RM5 = RM20.
Awas: Jangan bundarkan ke atas. Baki yang belum cukup RM200 tidak layak menerima rebat.
每满额回扣 = Rebate for every full amount
The RM10 rebate is given only for every complete RM200. Divide RM730 by RM200, keep the whole number only, then multiply by RM10.
Example: Example: RM5 rebate for every full RM100. Spending RM460 contains 4 full RM100s, so the rebate = 4 × RM5 = RM20.
Watch out: Do not round up. The remainder that has not reached RM200 does not earn any rebate.
第 7 题
一套音响原价 RM450,先打 20% 折扣,付款时每满 RM100 回扣 RM8。净支出是多少?
折扣与满额回扣 = Diskaun diikuti rebat
Kira diskaun dahulu kerana ia berlaku semasa membeli. Rebat dikira berdasarkan amaun yang benar-benar dibayar selepas diskaun, mengikut berapa kali RM100 penuh terkandung di dalamnya.
Contoh: Contoh: harga RM300, diskaun 10% menjadi RM270. Setiap RM100 penuh rebat RM5, jadi rebat = 2 × RM5 = RM10. Bersih = RM260.
Awas: Jangan kira rebat daripada harga asal. Selepas diskaun, bilangan RM100 penuh mungkin berkurang.
折扣与满额回扣 = Discount followed by rebate
Work out the discount first because it happens at purchase. The rebate is based on the amount actually paid after the discount, counting how many full RM100s it contains.
Example: Example: price RM300 with 10% discount becomes RM270. RM5 for every full RM100 gives 2 × RM5 = RM10. Net = RM260.
Watch out: Do not count the rebate from the original price. After the discount, the number of full RM100s may be smaller.
第 8 题
一双球鞋原价 RM240,折扣后售 RM204。折扣率是多少?
折扣率 = Kadar diskaun
Kadar diskaun ialah potongan harga dibandingkan dengan harga asal. Tolak harga selepas diskaun daripada harga asal untuk mendapat potongan, kemudian bahagikan dengan harga asal dan darab 100%.
Contoh: Contoh: harga asal RM80, harga jual RM64. Potongan RM16. Kadar diskaun = 16 ÷ 80 × 100% = 20%.
Awas: Peratus harga yang dibayar bukan kadar diskaun. Jangan juga tulis potongan dalam ringgit sebagai peratus.
折扣率 = Discount rate
The discount rate compares the price cut with the original price. Subtract the sale price from the original price to get the cut, then divide by the original price and multiply by 100%.
Example: Example: original RM80, sale price RM64. The cut is RM16. Discount rate = 16 ÷ 80 × 100% = 20%.
Watch out: The percentage of the price you still pay is not the discount rate. Also do not write the ringgit cut as a percentage.
