Hello everyone let’s study Matrix arrangement let’s go to Matrix arrangement part 1 so what is matrix arrangement basically the data on different parameters are to mapped with each other so for example let say there are Three Students A B and C and their IV sports tennis Hockey cricket and football B likes to play tennis and C likes to play cricket so in this manner some information will be given about different students who like different sports and probably something else also so we need to make a grid and map student A like the sports and do something else so this is matrix arrangement let’s see an example and see how to solve that question so for example 7 friends B, R, K, M, Y, T and F study in 3 different Schools that is A, C and X. Not more than 3 or less than 2 study in any of the schools. Each one has a favorite fruits among pineapple, Banana, Pear, Mango, Watermelon, Sweet lime and Papaya not necessarily in that order. R studies in school X and likes mango where as Y studies in school A and likes pineapple. None in school C likes the fruit pear. T studies in the same school only Y where as M does not study in school C. M likes papaya where as F like watermelon B does not like sweet lime and only two of them study in school X so if you have observe carefully there are three parameters one is friend second is school and the third is fruit so we have 3 columns let’s see how to solve this question step by step so we have one column for student another for school and the next for fruit now in school there are again two columns tick and cross what does tick means it means if B is going to some school then we will write down under tick column if the students are not going to some school then we will write under cross column and similarly for fruits also the first statement
