3 টি ক্রমিক ছাড় = 12%, 20%, 25%
ব্যবহৃত সূত্র:
সমতুল্য ছাড় = a + b - (a x b)/100
যেখানে a এবং b দুটি ক্রমিক ছাড়।
গণনা:
12% এবং 20% এর সমতুল্য ছাড় = 12 + 20 - (12 × 20)/100 = 32 - 2.4 = 29.6%
এখন, 29.6% এবং 25% এর সমতুল্য ছাড়
⇒ 29.6 + 25 - (29.6 × 25)/100 = 54.6 - 7.4 = 47.2%
∴ 12%, 20% & 25% এর সমতুল্য ছাড় 47.2%
অতএব, সঠিক উত্তর হল 47.2%।
