Answer» 1,984Explanation:Given:Principal (P) = 2000Rate of Interest (R%) = 10%AMOUNT (A) = 2420To find:Time (n) = ?The FORMULA to find the amount (A)\boxed{\BF Amount=P(1+\FRAC{R}{100})^{n}} Amount=P(1+ 100R ) n \implies \bf 2420=2000(1+\frac{R}{100})^{n}⟹2420=2000(1+ 100R ) n \implies \bf \frac{2420}{2000}=(1+\frac{R}{100})^{n}⟹ 20002420 =(1+ 100R ) n \implies \bf \frac{242}{200}=(1+\frac{1}{10})^{n}⟹ 200242 =(1+ 101 ) n \implies \bf \frac{242}{200}=(\frac{10+1}{10})^{n}⟹ 200242 =( 1010+1 ) n \implies \bf \frac{242}{200}=(\frac{11}{10})^{n}⟹ 200242 =( 1011 ) n \implies \bf \frac{2\times 11\times 11}{2\times10 \times 10}=(\frac{11}{10})^{n}⟹ 2×10×102×11×11 =( 1011 ) n \implies \bf \frac{11\times 11}{10\times 10}=(\frac{11}{10})^{n}⟹ 10×1011×11 =( 1011 ) n \implies \bf (\frac{ 11}{ 10})^{2}=(\frac{11}{10})^{n}⟹( 1011 ) 2 =( 1011 ) n Now bases are same, we can compare the exponents,⇒ 2 = nHence,Time (n) = 2 years |
