Question

(C) 62500 for 1(1/2)years at 8% per annum compounded half yearly.​

Answer 1

Amount after 1.5 year =62500(1+4/100)^3=62500×26/25×26/25×26/25=70304

Interest=70304-62500=7804

Answer 2

Step-by-step explanation:

here

P = 62500

time= 1(1/2).= 3/2years { per annum}

rate % = 8%

for compounded half yearly

time =( 3/2) × 2 = 3. (half yearly)

rate%= 8/2%. = 4 %

therefore by compound interest

Amount = P ( 1+r/100)^t

$= 62500(1 + \frac{4}{100} ) { }^{3 } \\ = 62500( \frac{26}{25} ) {}^{3} = 62500( \frac{26 \times 26 \times 26)}{25 \times 25 \times 25)} \\ = 4 \times 26 \times 26 \times 26 \\ = 70304 \: \:$

we get amount =70304

compound interest = 7804
