Problem 8: A shopkeeper sales a pen for 13.20 Rs and gets a profit of 10%. If he wants to increase his profit to the limit of 15%, then at what price should he sale the pens ?
a) 13.53 Rs b) 13.72 Rs c) 13.80 Rs d) 13.86 Rs
Solution:
We suppose Cost Price (CP) of Pen is ‘x’
i-e
We are given that Sale Price (SP) is 13.20 Rs
i-e
Also given that profit is 10 % of CP i-e;
We know the profit formula
Put respective values
Shifting ‘x’ terms to one side
Simplifying,
So, we have calculated CP as Rs 12
Now Come to Condition
If we want to earn 15% profit of cost price i-e
Then what should be the SP ?
We Know
Put values of condition !
Shift ‘x’ terms to one side
or
Put value of x
So he should sale it for 13.80 Rs for earning 15% profit
