Answer 1

Given :

• Profit% = 10%

Formula used :

• Profit = SP - CP
• Profit % = (Profit× 100)÷ CP

Procedure :

• Firstly find Profit
• then find SP of 90 article
• Then find SP of 1 article

Solution :

Profit % = (Profit× 100)÷ CP

$\sf \implies \: 10 = \dfrac{ (Profit \times 100) }{2500} \\ \\ \sf \implies \: Profit = \dfrac{ ( 2500\times 10) }{100} \\ \\ \sf \implies \: Profit = 250$

➠ Profit = SP of 90 article - CP of 90 article

➠ ₹250 = SP of 90 article - ₹2500

➠ SP of 90 article= ₹(2500+250)

➠ SP of 90 article = ₹2750

Therefore

➠ SP of 1 article = SP of 90 article ÷ 90

➠ SP of 1 article = (₹2750)÷90

➠ SP of 1 article = ₹30.56

ANSWER :

SP of 1 article = ₹30.56
