27 = x mod 5 9 = 1 mod y Find the min value of x^2 + y^2? Please explain on how to solve this question!

X = 2 (that is the remainder when 27 is divided by 5)9 = y*k + 1 where k is a natural number.The smallest absolute value of y which satisfies the above equation is 2 as 9 = 1 (mod 2)So, the minimum value of x^2 + y^2 = 5.Do go through these number systems cheatsheet for CAT.

What I did was I subtracted (8400+9680) from 25088, which is principle for third year using CI formula. They have subtracted the amount which was paid at the year end to get Principle for next year. Is it a valid concept of C.I. and I missed something?

Hi,What you have missed is "the time value of money". Rs. 8400 paid at the end of the first year is different from Rs. 8400 paid at the end of the third year. The most fundamental thing about comparing money is that everything must be brought to the same time frame.If you wish to compare by the beginning of 3 years, Rs. 20000 would have amounted to 25088 by the beginning of three years.8400 is paid at the end of the first year. => 8400 will amount to 9408 by the end of 2 years (i.e 8400 compounded at 12% for 1 year)25088-9408-9680 = 6000 This pdf of simple and compound interest formulae for CAT can be of help to you.

Permutation And Combination:In a boat, that to be filled by 8 people, there are 4 seats on left and 4 on right. Out of these 8 people 3 insist to sit on left and 2 insist to sit on right. So in how many ways they all can sit.

The number of ways in which we can find seats for the people insisting on sitting on one side of the boat is 4P3*4P2 = 288The other three people can be arranged in 3! = 6 ways.Hence, the total number of ways in which they can sit is 288*6 = 1728You can find the formula sheet for Permutations and Combinations for CAT here.
