Now all you have to do is figure out the range which is the y value. At first glance I think it might be 3, but that does not look very logical. I'll post this much of it now and be back in under an hour with a more complete answer.

Of course! How silly of me. There is a minimum of y = 1 in the range which comes from x = 0

I've included a graph so you can see how this all works.

So the range = 1 ≤ y ≤ 3

What price should Kiran mark on a sari, which costs Rs 3000 so as to gain 20% after allowing a discount of 10% ?

vaieri [72.5K]

Purchase price = Rs. 3000

Let the price marked on the Sari be x

After 10% discount, Kiran still makes 20% gain.

After discount, the price of the Sari = (100-10)%*x = 90% of x = 0.9x

Then,
(0.9x - 3000)/3000 = 0.2
0.9x - 3000 = 3000*0.2 = 600
0.9x = 3000+600 = 3600
x = 3600/0.9 = 4000

Therefore, priced marked on Sari should be Rs. 4000.
