1. A consulting firm was once planning to open a new branch in a Bangalore, and advertised for three positions for Accountants. Out of number of applicants the HR Manager selected two and one young men and woman and addressed them in the following way: “Your salaries will begin at the rate of $1,000 per year, to be paid half yearly. If your work is satisfactory, and we will keep you, your salary will be raised. Which one would you prefer, a raise of $150 per year or a raise of $50 every half-year? The first two applicants eagerly accepted the first alternative, but the third applicant, after a moment’s reflection too the second. Why?
2. Nithin drove his nano car 1 mile to the top of nilgiri hills at the rate of 15 miles per hour. How fast must he drive 1 mile down the other side in order to average 30 miles per hour for the whole trip of 2 hours?
