1. The owner of J3K invested an amount of P30 000.00 separately. The first at 6%, the second at 7% and the third at 9%. In one year, the profit was P2210.00. However, if the first amount was invested at 9%, the second at 7% and the third at 6%, the profit would only be P2180. Find the three amounts invested.

2. A group of 14 people spent P560.00 for admission tickets to a certain show. Gate A charges P50.00 for adults, P30.00 for students and P20.00 for children. If the same people could have entered through Gate B which charges P80.00 for adults, P40.00 for students and P20.00 for children, they could have spent P840.00. How many adults, students and children are there?
