Tim, Flynn and Colin collected stamps in the ratio of 10 : 8 : 5. After Colin gave
35 to Tim and Flynn, Colin had 188 less stamps than Tim. The number of stamps that Flynn had increased by 20%. How many stamps did Tim and Colin have in the end?

| Before |
10 u |
8 u |
5 u |
| Change |
+ 1.4 u |
+ 1.6 u |
- 3 u |
| After |
11.4 u |
9.6 u |
2 u |
Number of stamps that Colin gave to Tim and Flynn
=
35 x 5 u
= 3 u
Number of stamps that Flynn received from Colin
=
20100 x 8 u
= 1.6 u
Number of stamps that Tim received from Colin
= 3 u - 1.6 u
= 1.4 u
Number of less stamps that Colin had less than Tim
= 11.4 u - 2 u
= 9.4 u
9.4 u = 188
1 u = 188 ÷ 9.4 = 20
Number of stamps that Tim and Colin had
= 11.4 u + 2 u
= 13.4 u
= 13.4 x 20
= 268
Answer(s): 268
