Neave bought 48 more pens than Oscar and Oscar bought 28 pens more than Fanny. The total number of pens Neave and Oscar bought was 4 times the number of pens Fanny bought.
- How many pens does Neave need to give Oscar so that they have the same number of pens?
- How many pens did all three of them have altogether?
Neave |
Oscar |
Fanny |
1 u + 28 + 48 |
1 u + 28 |
1 u |
4 u |
1 u |
(a)
Number of pens that Neave needs to give Oscar so that they have same number of pens
= 48 ÷ 2
= 24
(b)
Total number of pens that Neave and Oscar had
= 1 u + 28 + 48 + 1 u + 28
= 1 u + 1 u + 28 + 48 + 28
= 2 u + 104
4 u = 2 u + 104
4 u - 2 u = 104
2 u = 104
1 u = 104 ÷ 2 = 52
Total number of pens that all three of them had
= 4 u + 1 u
= 5 u
= 5 x 52
= 260
Answer(s): (a) 24; (b) 260
