Answer:
Cost price of 80 articles = Rs. 2400
Profit on 80 articles =16%
∴ Profit (Rs.) =
[tex] \frac{16}{100} \times 2400 = 384[/tex]
Selling Price of 80 articles = Cost Price + Profit
=2400+384
=Rs. 2784
∴ Selling price of 1 article =
[tex] \frac{2784}{80} = 34.8[/tex]
So, the selling price of 1 article is Rs. 34.8.

Step-by-step explanation:
Solution for Question 1:
[tex] \sf{Profit \: \% = \dfrac{Profit}{CP} \times 100} \\ \\ [/tex]
[tex]\implies \sf{Profit \: \% = \dfrac{SP - CP}{CP} \times 100 } \\ \\ [/tex]
[tex] \implies \sf{Profit \: \% = \dfrac{24500 - 24000}{24000} \times 100} \\ \\ [/tex]
[tex] \implies \sf{Profit \: \% = \dfrac{500 \times 100}{24000} } \\ \\ [/tex]
[tex] \therefore \: \boxed{ \boldsymbol{Profit \: \% = 2.083 \: \% }} \\ \\ [/tex]

Solution for Question 2:
Write the given numbers in the form of fractions.
[tex]\sf{\dfrac{15}{45} \: \: and \: \: \dfrac{40}{120} } \\ \\ [/tex]
On simplifying, we get:
[tex] \sf{ \dfrac{1}{3} \: \: and \: \: \dfrac{1}{3} } \\ \\ [/tex]
So, the given numbers are in proportion.
