**Dear Aspirants,**

**Directions (1-5): The table shows the time (hours) taken by two trains X and Y in a week days (Monday to Friday). **

**Study the data carefully and answer the questions. **

**Train X and Train Y travel same distance 720 km every day. **

**Q1. What is the average speed of train X from Monday to Friday?**

**Q2. Speed of train Y in all over the week days is how much approximate percent more or less than speed of train X in all over the week days.**

**Q3. If the speed of train Y increased by 20% on Thursday, then find the time taken by train Y to cover the same distance?**

**Q4. Find the ratio between the speed of train X on Tuesday and Thursday together to the speed of train Y on same days?**

**Q5. Find the difference between the total speed of train X and train Y on Wednesday and Monday together and speed of train X and train y on Friday?**

**Q6. X and Y together can do a work in12 days and Z alone can do the work in 60 days. If X can do a certain work in the same time in which Y and Z together can do it, then find y alone could do the work in how many time?**

**Q7. Ram can do a work in 30 days and Shyam is 25% more efficient than Ram. In how many days they complete the double of the same work starting together?**

**Q8. On selling 12 books at 1800 the profit is equal to the cost price of 3 books. Find the cost price of each book ?**

CP of 3 books = SP of 12 books – CP of 12 books

CP of 15 books = SP of 12 books

CP of 15 books = 1800

CP of 1 book = 1800/15

= Rs 120

**Q9. How many 6 digits land line numbers can be formed using the digits from 0 to 9 if repetition is allowed and 0 (zero) can also start the number?**

**Q10. Find the probability of getting a total score equal to a prime number on throwing two dice simultaneously.**

Favorable event = [(1, 1), (1, 2), (1, 4), (1, 6), (2, 1), (2, 3), (2, 5), (3, 2), (3, 4), (4, 1), (4, 3), (5, 2), (5, 6), (6, 1), (6, 5)]

Required probability = 15/36

= 5/12
