Question

Mohan sold to article at the rate 800 and 1000 at a loss of 8% and a gain at 15% calculate the CP of both the articles​

Answer 1

Answer:

Profit of 5%

Step-by-step explanation:

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

Answer 2

Answer:

Sold means SP. Let two articles be A and B

let article A's SP be 800₹. loss = 8%.

• Formula to calculate cost price if selling price and loss percentage are given: CP = ( SP × 100 ) / ( 100 – percentage loss ).

CP = ( 800 × 100 ) / ( 100 - 8 ).

= ( 80000 ) / ( 92 )

= 20000/23₹

let article B's SP be 1000₹. gain = 15%.

• Formula to calculate cost price if selling price and profit percentage are given: CP = ( SP * 100 ) / ( 100 + percentage profit).

CP = ( 1000 × 100 ) / ( 100 + 15 )

= ( 100000 ) / ( 115 )

= 20000/23₹

HOPE THIS HELPS :D
