কোনো পণ্যের বিক্রয়মূল্য দ্বিগুণ হয়ে গেলে লাভ চারগুণ হয়ে যায়।
অনুসৃত সূত্র:
লাভ = বিক্রয়মূল্য (S.P) - ক্রয়মূল্য (C.P)
লাভ % = {লাভ (P) × 100}/C.P
গণনা:
প্রশ্নানুসারে:
⇒ 4 × (S.P - C.P) = (2 × S.P - C.P)
⇒ 4 S.P - 4 C.P = 2 S.P - C.P
⇒ 2 S.P = 3 C.P
⇒ S.P/C.P = 3/2
শতকরা লাভ = (P × 100)/100
⇒ {(3 - 2) × 100}/2 = 100/2 = 50%.
∴ সঠিক উত্তর 50%
