There was an equal number of red and pink beads in a packet at first. After 16 pink beads were taken out and 46 red beads were added into the packet, there was
13 as many pink beads as red beads. Find the number of pink beads in the packet at first.

Red beads |
Pink beads |
Before |
3 u - 46 |
1 u + 16 |
Change |
+ 46 |
- 16 |
After |
3 u |
1 u |
The number of red and pink beads in the packet is the same at first.
3 u - 46 = 1 u + 16
3 u - 1 u = 16 + 46
2 u = 62
1 u = 62 ÷ 2 = 31
Number of pink beads at first
= 1 u + 16
= 31 + 16
= 47
Answer(s)47
