should she sell for Rs 112 to gain 20% on the whole ?
Hi,
When she sells for Rs160, loss is 20%.
If C is her cost price then C(1-0.2) = 160 => C=200.
So, cost of each orange is 200/45 = 40/9
Now, she sells some more oranges(n) for 112 to make profit of 20% on the whole.
So, total selling price is 160+112 = 272.
Cost price of (45+n) oranges = 272/1.2 = 680/3
So, 45+n = (680/3)/(40/9) = 51.
So, n =6
So she should sell 6 oranges for Rs 112.
