At the farm, the turkey population increased by 30% in the second month and then by a further 10% in the next 4 months. If there were 429 turkeys in the end, how many turkeys were there at the farm at first?

Turkeys |
| Before |
100% |
| Change 1 |
+ 30% |
| After 1 |
130% |
| Change 2 |
+ 13% |
| After 2 |
143% |
Population of turkeys at first = 100%
New population of turkeys after first increase
= 100% + 30%
= 130%
Percentage of second increase
= 10% x 130%
=
10100 x 130%
= 13%
New population of turkeys after second increase
= 130% + 13%
= 143%
143% of turkey population = 429
1% of the turkey population
= 429 ÷ 143
= 3
100% of turkey population
= 100 x 3
= 300
Number of turkeys at first = 300
Answer(s): 300
