Question

the ratio of the number of boys to the number of girls is 3 : 2. if each boy receives 2 pieces of paper and each girl receives 3 pieces of paper, how many children are there altogether if a total of 1992 pieces of paper are needed?

im not sure if this is right, but i got 797 children

Answer 1

since each group of 3 boys and 2 girls gets a total of 3*2+2*3=12 pieces of paper, there are

1992/12 = 166 groups of 5 children, or 830 in all
