Harry bought 72 more pens than Flynn and Flynn bought 12 pens more than Nora. The total number of pens Harry and Flynn bought was 5 times the number of pens Nora bought.
- How many pens does Harry need to give Flynn so that they have the same number of pens?
- How many pens did all three of them have altogether?
Harry |
Flynn |
Nora |
1 u + 12 + 72 |
1 u + 12 |
1 u |
5 u |
1 u |
(a)
Number of pens that Harry needs to give Flynn so that they have same number of pens
= 72 ÷ 2
= 36
(b)
Total number of pens that Harry and Flynn had
= 1 u + 12 + 72 + 1 u + 12
= 1 u + 1 u + 12 + 72 + 12
= 2 u + 96
5 u = 2 u + 96
5 u - 2 u = 96
3 u = 96
1 u = 96 ÷ 3 = 32
Total number of pens that all three of them had
= 5 u + 1 u
= 6 u
= 6 x 32
= 192
Answer(s): (a) 36; (b) 192
