Answer:
<em>The shopkeeper purchased the pen at Rs. 50</em>
Step-by-step explanation:
<u>Equations</u>
Let's set
x = Original purchase price of the pen
The shopkeeper fixed the price of the pen to make a profit of 10%.
It means the retail price was going to be:
x + 10% x = x + 10x/100 = x + 0.1x = 1.1x
The retail price was fixed to 1.1x but the pen sold with a discount of Rs 7.50, thus the real retail price was
1.1x - 7.50
The shopkeeper lost 5% in the operation, thus:
1.1x - 7.50 = x - 5% x = x - 0.05x = 0.95x
The equation to solve is:
1.1x - 7.50 = 0.95x
Adding 7.50:
1.1x = 0.95x + 7.50
Subtracting 0.95x:
1.1x - 0.95x = 7.50
Operating:
0.15x = 7.50
Dividing by 0.15:
x = 7.50 / 0.15
x = 50
The shopkeeper purchased the pen at Rs. 50
