Answer 2

Answer:

:

Let CP is x

Sp = 90%of x (because of 10%loss)

Now if he had sold 45/- more,

Then 90%x + 45/- then the profit will be 5% or (105%x)

Or 90%x + 45/- = 105%x

(90x + 4500) / 100 = 105x / 100

Cancelling 100 from denominator

We get,

90x + 4500 = 105x

Or, 15 x = 4500

X = 300.

Or Cp is 300/-
