PLZZ follow me ❤️❤️❤️❤️❤️

Let the cost price be 100

we need profit of 20%

So, profit = 100*20% = 20

Cost + Profit = 100 + 20= 120

we need 120 after 10% discount on Sales, effectively 120 should be 90% (100%–10%)

If 120 is 90%, we find 100% : 120/90*100= 133.33

So the 33.33% must be addes to the cost so that profit of 20% is made after giving 10% discount

Here is the check

If Cost is 100, we add 33.33% to it, that makes it 133.33

Now 10% discount on 133.33 will be 13.33

After discount it will be 120 (giving 20 as profit)
