Question

the simple interest on a certain sum of money for 2 years at 5 whole 1 by 2% is rupees 6600 what will be the compound interest on that sum at the same rate for the same time period​

Answer 1

Step-by-step explanation:

SI =Rs 6600

time= 2yrs

rate= 5whole 1by 2%

= 11/2%

P = si*100/(r*t)

= (Rs 6600*100)/11/2*2

= (Rs 6600*100)/11

= Rs 60000

CI=6600+3300*(11/2)*(1/100)

= 6600+ 181.5

= 6781.5

Answer 2

Answer:

6781.50

Step-by-step explanation:

given

time=2yrs

R%=5 1/2%

=11/2%

S.I =6600

solution -

S.I.= (P×R×T)÷100

$6600 = \frac{p \times 11 \times 2}{100 \times 2}$

$6600 = \frac{11}{100} \times p$

$p = 6600 \times \frac{100}{11}$

$p = 600 \times 100$

$p = 60000$

C.I.=

$p((1 + \frac{r}{100} ) ^{n} - 1)$

$c.i \:. = 60000((1 + \frac{11}{200} )^{2} - 1)$

$\: \: \: = 60000(( \frac{211}{200} ) ^{2} - 1)$

$\: \: \: \: = 60000( \frac{44521}{40000 \: } - 1)$

$\: \: \: \: \: \: \: \: \: = 60000 \times \frac{4521}{40000}$

$\: \: \: \: \: \: \: \: \: \: \: = \frac{13563}{2}$

= 6781.50
