Answer:
Given:
The profit obtained on selling smartphones is Rs. 2500/piece
The profit obtained on selling old mobiles is Rs. 900/piece
The net profit obtained by the shopkeeper during a period of a month = Rs. 17900
No. of android phones sold by the shopkeeper in 1 month = 5
To find:
No. of old mobiles sold by the shopkeeper in the period of a month
Solution:
So,
The profit obtained on selling 5 smartphones would be,
= Rs. 2500 × 5
= Rs. 12500
Let "x" represent the no. of old mobiles sold by the shopkeeper 1 month.
Now, according to the question, we can form an equation for the net profit so obtained during the period of a month, which is as follows:
[Profit obtained on selling 5 android phones] + [Profit obtained on selling x old mobiles] = [Net profit obtained]
\begin{gathered}\implies 12500 + (900x) = 17900\\\end{gathered}⟹12500+(900x)=17900
\implies 900x = 17900 - 12500⟹900x=17900−12500
\implies 900x = 5400⟹900x=5400
\implies x = \frac{5400}{900}⟹x=9005400
\implies \bold{x = 6}⟹x=6
Thus, the shopkeeper had sold 6 old mobiles during that period.
Answer:
2500-30,000=27400
