second year CI is 840

total CI in two years is 1640

Answer 2

Given :

P = ₹16000,

R = 5%

N= 2 years

To find :

compound interest on ₹16000 for 2years at 5% per annum

solution :

$A = P {(1 + \frac{R}{100} ) }^{N} \\ \\ = 16000 {(1 + \frac{5}{100} )}^{2} \\ \\ = 16000{( \frac{105}{100} )}^{2} \\ \\ = \frac{16 \cancel{000} \times 11025}{10 \cancel{000}} \\ \\ = \frac{17640 \cancel{0}}{1 \cancel{0} } \\ \\ \underline{ A=17640 } \\ \\ \\ so ,\: compound \: interest = 17640 - 16000 \\ = 1640 \\ \\ \underline{\boxed{\sf{C.I = 1640 }}}$
