প্রদত্ত:

12% এবং 10%-এর দুটি ক্রমিক ছাড়।

অনুসৃত সূত্র:

সমতুল্য ছাড় = 100% - [(100% - ছাড়1) × (100% - ছাড়2)]/100%

যেখানে ছাড়1 এবং ছাড়2 হল প্রদত্ত দুটি ক্রমিক ছাড়

সমাধান:

সূত্রে ছাড়1 = 12% এবং ছাড়2 = 10% প্রতিস্থাপন করে পাই:

সমতুল্য ছাড় = 100% - [(100% - 12%) × (100% - 10%)]/100%

= 100% - [(88%) × (90%)]/100%

= 100% - 79.2%

= 20.8%

অতএব, 12% এবং 10% এর দুটি ক্রমিক ছাড়ের সমতুল্য একক ছাড় হল 20.8%
