a class of 20 boys and 15 girls is divided into n groups so that each group has x boys and y girls. find x, y, n.

n needs to be a factor of 20 n 15 to divide them equally.

20 = 5 * 2 * 215 = 5 * 3

therefore no. of groups(n) = 5

also,if each group has equal no. of boys (x),

then x= 20/5

x=4

similarly y = 15/5

y = 3

thumbs up plz....

in second line it is

20= 5*2*2 (space) 15= 5*3
