Download Solution PDFGiven:
X bought 40 pencils for a total of Rs. 180.
X bought 2 dozen (24 units) pens for Rs. 180.
Calculation:
Let's denote the price of one pencil as 'P' and the price of one pen as 'Q'.
For Pencil
180 = 40 × P
So, we can calculate the price of one pencil as:
P = 180/40 = Rs. 4.5
For Pen
180 = 24 × Q
So, the price of one pen is:
Q = 180/24 = Rs. 7.5
Difference = 7.5 - 4.5 = Rs. 3
Therefore, the difference between the price of one pen and one pencil is Rs. 3.
