40% এবং 20% ক্রমিক ছাড়ের সমতুল্য একক ছাড়
ব্যবহৃত সূত্র:
একক ছাড় = 1 - (1 - d1) × (1 - d2)
গণনা:
একক ছাড় = 1 - (1 - 0.40) × (1 - 0.20)
⇒ একক ছাড় = 1 - 0.60 × 0.80
⇒ একক ছাড় = 1 - 0.48
⇒ একক ছাড় = 0.52 = 52%
∴ সঠিক উত্তরটি হলো বিকল্প (4)।
একক ছাড় = D1 + D2 - (D1 × D2)/100
⇒ 40 + 20 - 40 × 20 /100 = 60 - 8 = 52%
