Question

If a box containing red and white marbles, half the number of white

marbles is equal to one-third the number of red marbles. Thrice the total

number of marbles exceeds seven times the number of white marbles by

6. How many marbles of each colour does the box contain?​

Answer 1

Let the white marvel be w

and red marvel be. r

AtoQ

w/2=r/3; 3w=2r

3(r+w)=7+w

=3r+3w=7+w

=3r+2r=7+2r/3

=5r-2r/3=7

=(15r-2r)/3=7

=13r=21

=r=21/13

w=2r/3; w=42/39
