Question

the difference between C.I and S.I on the sum of money at 10% p.a. for 2 year is Rs.500. find the sum?​

Answer 1

$so \: first \: lets \: take \: out \: compound \: imterest$

principal = 500

Rate = 10%

Time = 2 yrs

$amount \: = p( \frac{1 + r}{100} )^{n} where \: n = time$

$= 500( \frac{1 + 10}{100} ) ^{2} \\ = 500( \frac{110}{100} \times \frac{110}{100} ) \\ = 121 \times 5 \\ rs \: 605$

Amount = RS. 605

compound interest = amount - principal

= 605 - 500

COMPOUND INTEREST = Rs 105

Similarly, for simple interest

principal = 500

Rate = 10%

Time = 2 yrs

$simple \: interest \: = ( \frac{p \times t \times r}{100} )$

$( \frac{500 \times 10 \times 2}{100} )$

SIMPLE INTEREST = Rs.100

DIFFERENCE = COMPOUND INTEREST - SIMPLE INTEREST

= 105-100

SO, DIFFERENCE = 5 RUPEES
