1. The ratio of girls to boys is 5:6. On a rainy day, 1/6 of girls and 1/4 of boys were absent. If the total number of pupils present was 390, how many of the pupils were boys?

2. Two cars X and Y start at the same point and travel toward point P which is 150km away.

If the average speed of Y is 60km/h and X arrives at P 25 minutes earlier, what is the average speed of X?

3. A & B can do a piece of work in 15 days. They both started, but after 6 days B gets ill and A takes 30 more days to finish the job himself. How long would each take working alone?
