A transporter receives the same number of orders each day. Currently he has some pending orders to be shipped. If he uses 7 trucks then at the end of 4th day, he can clear all the orders. Alternatively If he uses only 3 trucks, then all the orders are cleared at the end of 10th day. What is the minimum number of trucks required so that there will be no pending order at the end of the 5th day?
