Flynn, Lee and Cooper collected marbles in the ratio of 7 : 5 : 8. After Cooper gave
45 to Flynn and Lee, Cooper had 232 less marbles than Flynn. The number of marbles that Lee had increased by 120%. How many marbles did Flynn and Cooper have in the end?

Flynn |
Lee |
Cooper |
| Before |
7 u |
5 u |
8 u |
| Change |
+ 0.4 u |
+ 6 u |
- 6.4 u |
| After |
7.4 u |
11 u |
1.6 u |
Number of marbles that Cooper gave to Flynn and Lee
=
45 x 8 u
= 6.4 u
Number of marbles that Lee received from Cooper
=
120100 x 5 u
= 6 u
Number of marbles that Flynn received from Cooper
= 6.4 u - 6 u
= 0.4 u
Number of less marbles that Cooper had less than Flynn
= 7.4 u - 1.6 u
= 5.8 u
5.8 u = 232
1 u = 232 ÷ 5.8 = 40
Number of marbles that Flynn and Cooper had
= 7.4 u + 1.6 u
= 9 u
= 9 x 40
= 360
Answer(s): 360
