ধারাবাহিক ছাড় হল 5%, 10% এবং p%
একক ছাড় = 31.6%
ধারণা: MP-তে a%, b% এবং c% এর তিনটি ধারাবাহিক ছাড় থাকলে
SP = MP(100 - a)/100 × (100 - b)/100 × (100 - c)/100
ব্যবহৃত সূত্র:
SP = MP × (100 - D%)/100
D% = (D/MP) × 100
গণনা:
ধরাযাক MP হল x
SP = x × (100 - 5)/100 × (100 - 10)/100 × (100 - p)/100
⇒ SP = x × 95/100 × 90/100 × (100 - p)/100
⇒ x × 95/100 × 90/100 × (100 - p)/100 = x × (100 - 31.6)/100
⇒ x × 19/20 × 9/10 × (100 - p)/100 = x × 68.4 /100
⇒ (100 - p)/100 = 2 × 68.4/171
⇒ (100 - p)/100 = 0.8
⇒ (100 - p) = 80
⇒ p = 20
P এর মান 20%
