Question 107

Nisha bought a number of oranges at 2 for a rupee and an equal number at 3 for a rupee. To make a profit of 20% she should sell a dozen for

Solution

Let she bought 60 oranges of each type

Cost price of first type of oranges = 0.5 [ 1/2]

=> Total cost price of type 1 = 0.5*60 = 30

Similarly, total cost price of type 2 = $$\frac{1}{3}$$ * 60 = 20

=> C.P. = 30+20 = 50

Profit = $$\frac{20}{100}$$ * 50 = 10

=> Total S.P. = 50+10 = 60

Now, this selling price is for 120 oranges

For 12 oranges, S.P. = 12 * $$\frac{60}{120}$$ = 6
