Question

A shopkeeper sold 75 pens and pencils for ₹4915. The selling price of each pen was ₹120 and that of a pencil was ₹25. Find the Number of pens sold.

Answer 1

Let's take the number of pens be x and number of pencils be (75-x). Selling price of 75 pens and pencils =₹4915 =x(120)+(75-x)(25)=
=>4915=120x+1875-25x
=>4915=95x+1875
=>4915-1875=95x
=>3040=95x
=>3040\95=x
=>32=x.
So 32 pens are sold and 43 pencils are sold by the shopkeeper.
