Asher, Vaidev and Clark collected marbles in the ratio of 7 : 8 : 7. After Clark gave
710 to Asher and Vaidev, Clark had 250 less marbles than Asher. The number of marbles that Vaidev had increased by 60%. How many marbles did Asher and Clark have in the end?

Asher |
Vaidev |
Clark |
| Before |
7 u |
8 u |
7 u |
| Change |
+ 0.1 u |
+ 4.8 u |
- 4.9 u |
| After |
7.1 u |
12.8 u |
2.1 u |
Number of marbles that Clark gave to Asher and Vaidev
=
710 x 7 u
= 4.9 u
Number of marbles that Vaidev received from Clark
=
60100 x 8 u
= 4.8 u
Number of marbles that Asher received from Clark
= 4.9 u - 4.8 u
= 0.1 u
Number of less marbles that Clark had less than Asher
= 7.1 u - 2.1 u
= 5 u
5 u = 250
1 u = 250 ÷ 5 = 50
Number of marbles that Asher and Clark had
= 7.1 u + 2.1 u
= 9.2 u
= 9.2 x 50
= 460
Answer(s): 460
