Sainik School Entrance is a tough entrance examination to crack unless a very systematic approach is done the result would be negative. after years of training I have noticed the following flaws in the candidates preparation a) They do not practice the mathematical formulae which is essential to solve the problems b) Lack of understanding tha problem and what is asked is another area where they lose out marks. Let us take an example as to how should we go about solving a problem:- a) A man borrowed an amount of Rs.10,000 for a period of 73 days from a bank and agreed to pay a Simple interest at 15 1/2 % per annum. What would be interest and the total amount that he will repay the bank? Solution: Step 1: What are the data given? Principal Rs. 10000 SI 15.5 % Time 73 days
