There was an equal number of purple and pink beads in a box at first. After 25 pink beads were taken out and 23 purple beads were added into the box, there was
15 as many pink beads as purple beads. Find the number of pink beads in the box at first.

Purple beads |
Pink beads |
Before |
5 u - 23 |
1 u + 25 |
Change |
+ 23 |
- 25 |
After |
5 u |
1 u |
The number of purple and pink beads in the box is the same at first.
5 u - 23 = 1 u + 25
5 u - 1 u = 25 + 23
4 u = 48
1 u = 48 ÷ 4 = 12
Number of pink beads at first
= 1 u + 25
= 12 + 25
= 37
Answer(s)37
