Question

A profit of 24% was made when a book was sold for birr 34.10 find the selling price that would have given a profit of 28%.

Answer 1

Step-by-step explanation:

s.p=34.10

profit=24%

c.p=?

now,c.p=(100/100+gain)×s.p

=(100/100+24)×34.10

=100×34.10/124

=3410/124

=27.5.

again,selling price with 28%=(100+gain)×c.p/100

=(100+28)×27.5/100

=128×27.5/100

=3520/100
