Question

Two articles were sold for each rs1485 each. in one transaction there was a loss of 10% while in the other there was a profit of 10%. what was the percentage of profit or loss in overall transaction​

Answer 1

Answer:

1st article:-

Sp=1485

Loss%=10%

We find cp

Sp=(100-10%)=90

If sp if 90,cp is 100

If sp is 1 cp is 100/90

If sp is 1485,cp is 100/90×1485=1650

So cp of 1st article is rs1650

Now,

2nd article:-

Sp=1485

P=10%

Let sp be =(100+10)=110

If sp is 110,cp is 100

If sp is 1,cp is 100/110

If sp is 1485,cp is 100/110×1485=1350

So cp of 2nd artcle is rs 1350

Now we find total sp=sp of 1st article+sp of 2nd artlce=1485+1485=2970

Total cp=cp of 1st article +cp of 2nd articl=

1650+1350=3000

Total sp is 2970

Total cp is 3000

L=3000-2970=30

L%=l/cp ×100

30/3000*100=1%
