At the farm, the turkey population increased by 20% in the second month and then by a further 10% in the next 10 months. If there were 1320 turkeys in the end, how many turkeys were there at the farm at first?

Turkeys |
| Before |
100% |
| Change 1 |
+ 20% |
| After 1 |
120% |
| Change 2 |
+ 12% |
| After 2 |
132% |
Population of turkeys at first = 100%
New population of turkeys after first increase
= 100% + 20%
= 120%
Percentage of second increase
= 10% x 120%
=
10100 x 120%
= 12%
New population of turkeys after second increase
= 120% + 12%
= 132%
132% of turkey population = 1320
1% of the turkey population
= 1320 ÷ 132
= 10
100% of turkey population
= 100 x 10
= 1000
Number of turkeys at first = 1000
Answer(s): 1000
