Aditya sent us a very well explained solution to this problem:
Tim has 50% blue, 35% red, 10% white and 5% union jacks.
Beth has 40% blue, 32% red, 20% white and 8% union jacks.In fractions, this is:
T = \frac{1}{2} blue, \frac{7}{20}red, \frac{1}{10} white & \frac{1}{20} union jack.
= \frac{10}{20} blue, \frac{7}{20} red, \frac{2}{20} white and \frac{1}{20} union jacks.
Therefore Tim has 20 flags .
B = \frac{2}{5} blue, \frac{8}{25} red, \frac{1}{5} white & 2/25 \frac{2}{25} union jacks.
= \frac{10}{25} blue, \frac{8}{25} red, \frac{5}{25} white and \frac{2}{25} union jacks.
Therefore Beth has 25 flags .Now, we know that Beth has more flags than Tim. Beth has one more red flag, and both have the same number of blue flags. Between them, they have 3 union jacks.
Tim | Beth |
8 | 2 |
6 | 4 |
4 | 6 |
2 | 8 |
Tim | Beth | Tim has this number of flags | Beth has this number of flags | Total number of flags |
8 | 2 | 160 | 25 | 185 |
6 | 4 | 120 | 50 | 170 |
4 | 6 | 80 | 75 | 155 |
2 | 8 | 40 | 100 | 140 |
