Two articles for 1000 each

For first article

30% profit or gain means. SP = cost price + 30%of CP(cost price)

=1000 + 30/100 ×1000

=1000 +300 =1300

Similarly for

Second article

20% loss means SP (SELLING PRICE)=1000(CP)- (subtracting because it is loss) 20% of CP

= 1000–200(20% of CP) =800

now you asked overall gain or loss

So total money spend =1000+ 1000

total money get = 1300 + 800 =2100

So clearly it is profit or gain Bravo!

Now how much profit you gain

=total money get- total money spend

=2100 - 2000= 100

now gain percentage =profit ÷CP×100=100 /2000×100=5% gain
