Vaidev and Kathy had the same number of chocolate bars. After Kathy gave away 13 chocolate bars and Vaidev gave away 47 chocolate bars, Kathy had 3 times as many chocolate bars as Vaidev. How many chocolate bars did each of them have at first?
| |
Vaidev |
Kathy |
| Before |
1 u + 47 |
3 u + 13 |
| Change |
- 47 |
- 13 |
| After |
1 u |
3 u |
The number of chocolate bars that Vaidev and Kathy had at first is the same.
3 u + 13 = 1 u + 47
3 u - 1 u = 47 - 13
2 u = 34
1 u = 34 ÷ 2 = 17
Number of chocolate bars that each of them had at first
= 1 u + 47
= 17 + 47
= 64
Answer(s): 64
