Need help to solve the following Math questions. Many thanks in advance.
1. The ratio of the number of stalks of carnation to the number of stalks of roses in a floral shop was 5:2. Each stalk of carnation costs $4, while each stalk of rose costs $6. The florist would be able to collect $4800 from the sale pf all his roses and carnations.
(a)How many stalks of roses were there?
(b)After selling some roses, the ratio of carnations to roses became 10:1. How many stalk of roses were sold?
2. The table below shows the pricing of 3 types of tickets.
Ferry-$30 Train-$20 Bus-$10
The ratio of the number of ferry tickets sold to the number of train tickets sold was 5:6. The ratio of the number of train tickets sold to the number of bus tickets sold was 4:11. The amount of money collected from the sale of bus tickets was $270 more than the amount of money collected from the sale of ferry tickets. How much more money was collected from the sale of ferry tickets than the train tickets?
