According to the question,
30 pens + 75 pencils = Tk. 510
Average price of a pencil = Tk. 2 Price of 75 pencils = 2 × 75 = Tk. 150 ∴ Price of 30 pens = 510 - 150 = Tk. 360 ∴ Average price of pen = 360/30 = Tk. 12
30 pens + 75 pencils = Tk. 510
Average price of a pencil = Tk. 2 Price of 75 pencils = 2 × 75 = Tk. 150 ∴ Price of 30 pens = 510 - 150 = Tk. 360 ∴ Average price of pen = 360/30 = Tk. 12
