The Orange Vendor Problem is as follows :

**Question :**

After selling 35% of the oranges, a fruit vendor has 260 oranges left. How many did he have originally ?

a). 390

b). 520

c). 400

d). 300

**Solution : **

This may take like 15 seconds at max Ok look, he has sold 35% of his oranges and has 260 left. That means that 260 oranges is (100 – 35) = 65% of the total lot. So now if you do a simple cross multiplication, you’ll get :

Oranges Percentage

260 —— 65%

**x **? —— 100%

So cross multiplying we get

260 X 100 = 65 X **x**

**x** = (260 X 100) /65 = 400

Hence the total number of oranges that the vendor originally had was 400

Hence **answer is (c) 400**
