Answer 1

No of article = 150

Sp=150
Sp of each =1

Profit = 150%
Profit on each=150/100*Cp of each

Profit =Sp-Cp

150/100*Cp=1-Cp
250/100*Cp=1
Cp=100/250
Cp=0.4

Answer 2

Answer:

Rs 0.40

Step-by-step explanation:

Find the selling price of 1 article:

150 articles = Rs 150

1 article = 150 ÷ 150 = Rs 1

Find the cost price:

Selling Price = Cost Price + Profit

Selling Price = 100 + 150 = 250%

250% = Rs 1

1% = 1 ÷ 250 = Rs 0.004

100% = 0.004 x 100 = Rs 0.40

Answer: The cost price of 1 article is Rs 0.40
