Question

The cost price of 10 tables is equal to the selling price of 8 tables. Find the loss or profit percent.

Answer 1

Let the C.P. of each table $=Rs100$
C.P. of 10 tables $=Rs1000$
S.P. of 8 tables $=Rs1000$
So, S.P. of 1 table $=Rs125$
profit on 1 table $=Rs125-Rs100=Rs25$
or Profit percent $=\frac{25}{100}\times 100=25\%$
