Population of a village is 1,00,000. If population increases by 10% every year then find its population after 3 year.
Answer & explanation
Correct answer: option 4
Present Population × [1+\(\frac{10}{100}\)] × [1+\(\frac{10}{100}\)] × [1+\(\frac{10}{100}\)] = Population after 3 year
1,00,000 × \(\frac{11}{10}\) × \(\frac{11}{10}\) × \(\frac{11}{10}\) = Population after 3 year
1,00,000 × \(\frac{1331}{1000}\) = Population after 3 year
1,33,100 = Population after 3 year
