cp od product increase by 10% and selling price is same and profit is decreased by 20%
what is current profit %?

my approach is
cp=100x sp=120x p=20x
cp=110x sp=120x p=16x

but,
120x-110x = 10x

10x=16x
But cant able to solve further

Paras · Answer

we don't know what was the selling price earlier cause it is not mentioned what profit he gained earlier on which he get 20% value later!

Purbayan Dhar · Answer

let CP=x and SP=y. new CP=1.1x, SP=y
(y-x)4/5=y-1.1x 
x/y=2/3
take 20,30 for easier calculations.  new profit%= (30-22)/22*100= 36.36
