Question

There is 10% profit on selling a book. If the selling price would have been Rs 7 less,There would have been 4% loss .what is the cost price of the book

Answer 1

Let the CP be x
then
Profit = x/100*10
= x/10
SP = x+x/10
= 11X/10
If SP = 11x/10-7
Loss = 4 %
= 4/100*x
= x/25
Total SP = x-x/25
= 24x/25
Now ,
11x/10-7= 24x/25
70-11x = 48x/5
350 -55x = 48x
350= 103x
x= 350/103
= 3.39
