At a farm, there were
38 as many ducks and turkeys. The farmer added another 24 ducks but sold away 42 turkeys. In the end, there were 4 turkeys more than ducks. How many ducks and turkeys were there altogether in the end?
| |
Ducks |
Turkeys |
| Before |
3 u |
8 u |
| Change |
+ 24 |
- 42 |
| After |
3 u + 24 |
8 u - 42 |
If the farmer had another 4 ducks in the end, the number of ducks and (chickens) would be the same.
8 u - 42 = 3 u + 24 + 4
8 u - 3 u = 28 + 42
5 u = 70
1 u = 70 ÷ 5 = 14
Number of turkeys and ducks in the end
= 3 u + 24 + 8 u - 42
= 3 u + 8 u + 24 - 42
= 11 u - 18
= 11 x 14 - 18
= 136
Answer(s): 136
