Workers (at present) × [1+\(\frac{5}{100}\)] × [1+\(\frac{10}{100}\)] × [1+\(\frac{20}{100}\)] = Workers in the Fourth year

8000 × \(\frac{105}{100}\) × \(\frac{110}{100}\) × \(\frac{120}{100}\) = Workers in the Fourth year

8000 × \(\frac{21}{20}\) × \(\frac{11}{10}\) × \(\frac{6}{5}\) = Workers in the Fourth year

11088 = Workers in the Fourth year
