Sub-section I-A Number of Questions: 10 Note: Questions 1 to 10 carry one mark each. Directions for questions 1 to 8: Answer the questions independently of each other. 1. If R = jogging simultaneously from the point where one of the circular tracks touches the smaller side of the rectangular track. A jogs along the rectangular track, while B jogs along the two circular tracks in a figure of eight. Approximately, how much faster than A does B have to run, so that they take the same time to return to their starting point? (1) 3.88% (2) 4.22% (3) 4.44% (4) 4.72% 8. In a chess competition involving some boys and girls of a school, every student had to play exactly one game with every other student. It was found that in 45 games both the players were girls, and in 190 games both were boys.

Ram and Shyam run a race between points A and B, 5 km apart. Ram starts at 9 a.m. from A at a speed of 5 km/hr, reaches B, and returns to A at the same speed. Shyam starts at 9 : 45 a.m. from A at a speed of 10 km/hr, reaches B and comes back to A at the same speed. 9. At what time do Ram and Shyam first meet each other? (1) 10 a.m. (2) 10 : 10 a.m. (3) 10 : 20 a.m. (4) 10 : 30 a.m. 10. At what time does Shyam overtake Ram?
