Question

Find the loss or profit percent if its cost price is 9 upon 8 of its selling price

Answer 1

loss(L)=CP-SP

profit(P)=SP-CP

given cp=(9/8)sp

so sp=(8/9)cp

now loss=cp-sp=cp-(8/9)cp=1/9)cp

loss percntage=(L)/cp*100

=(1/9)cp/cp*100=100/9=11.11%

Answer 2

Step-by-step explanation:

Let the S. P. be X

and C. P. be (9/8)X

so,this means there is loss in whole transaction.

loss=(9/8)X - X

loss=(9X-8X)/8

loss=X/8

loss%=(profit/C.P.)×100

loss%={(X/8)/(9X/8)×100

loss%=(X/9X)×100

loss%=11.11%
