Question

A class of 20 boys and 15 girls is divided into new groups to teach them in different groups so that each group has x boys and y girls . Find x,y and n

Answer 1

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
