Owen, Glen and Clark collected pens in the ratio of 7 : 6 : 7. After Clark gave
710 to Owen and Glen, Clark had 265 less pens than Owen. The number of pens that Glen had increased by 75%. How many pens did Owen and Clark have in the end?

| Before |
7 u |
6 u |
7 u |
| Change |
+ 0.4 u |
+ 4.5 u |
- 4.9 u |
| After |
7.4 u |
10.5 u |
2.1 u |
Number of pens that Clark gave to Owen and Glen
=
710 x 7 u
= 4.9 u
Number of pens that Glen received from Clark
=
75100 x 6 u
= 4.5 u
Number of pens that Owen received from Clark
= 4.9 u - 4.5 u
= 0.4 u
Number of less pens that Clark had less than Owen
= 7.4 u - 2.1 u
= 5.3 u
5.3 u = 265
1 u = 265 ÷ 5.3 = 50
Number of pens that Owen and Clark had
= 7.4 u + 2.1 u
= 9.5 u
= 9.5 x 50
= 475
Answer(s): 475
