Question

what sum of money will amount to rs.21296 in 3 years at 10 percent per annum compounded annually

Answer 1

Answer:16000

Step-by-step explanation:

Amount = 21296

Term = 3 Years

Rate p.a = 10%

CI Amount formula = $P(\frac{100+R}{100} )^3$

$21296=P(\frac{110}{100})^3$

$\frac{21296}{P}=(\frac{110}{100})^3$

$\frac{21296}{P}=\frac{1331}{1000}$

$\frac{21296}{P}=\frac{1331*16}{1000*16} (as 1331 * 16 = 21296)$

$\frac{21296}{P}=\frac{21296}{16000}$

∴ Principle = 16000
