Glen, Ian and Curry collected marbles in the ratio of 8 : 7 : 10. After Curry gave

Curry |
| Before |
8 u |
7 u |
10 u |
| Change |
+ 5.2 u |
+ 2.8 u |
- 8 u |
| After |
13.2 u |
9.8 u |
2 u |
Number of marbles that Curry gave to Glen and Ian
=
45 x 10 u
= 8 u
Number of marbles that Ian received from Curry
=
40100 x 7 u
= 2.8 u
Number of marbles that Glen received from Curry
= 8 u - 2.8 u
= 5.2 u
Number of less marbles that Curry had less than Glen
= 13.2 u - 2 u
= 11.2 u
11.2 u = 336
1 u = 336 ÷ 11.2 = 30
Number of marbles that Glen and Curry had
= 13.2 u + 2 u
= 15.2 u
= 15.2 x 30
= 456
Answer(s): 456
