Question

there is decrease in sale of an object by 10 percent due to increse in the cost price of object by 10 percent then what is profit or loss percent in this transaction​

Answer 1

Answer:

Price increased by 10% and then decreased by 10%

let the price of an item be Rs.100

10%=10010=101

So 10% of 100=10010×100=10

New price after increase=100+10=110

Now 10% of 110 is =10010×110=11

So new price after decrease is Rs.110−11=Rs. 99

Rs.1 loss on Rs.100 means 1%
