Question

if A shopkeeper sells a table at 10% profit and other table at 5% loss what is his net percentage of loss or gain

Answer 1

assume cost price of each table is RS.100.

first table he sold for profit of 10% means he sold it for RS.110.

second table he sold @loss of 5% means he sold it for RS.95.

cost price of 2 tables is RS.200

selling price of 2 tables is RS.210

cp           sp

200      205

profit = s.p - c.p

profit = RS.5

5 is 2.5% of 200.

so 2.5% of  profit shop keeper earned.
