Question

b. * 434 is invested for 7/2 years at 5% per
annum

c. 4325 is invested for 73 days at 3% per month.​

Answer 1

Answer:

[D]7000 Rs.

7500 Rs.

Let the sum be P.

As, the interest is compounded half-yearly,

∴ R = 2%, T = 2 half years

$latex \therefore A = P \left ( 1+\frac{R}{100} \right )^{T}&s=1$

$latex => 7803 = P \left ( 1+\frac{2}{100} \right )^{2}&s=1$

$latex => 7803 = P \left ( 1+\frac{1}{50} \right )^{2}&s=1$

$latex => 7803 = P\times \frac{51}{50}\times \frac{51}{50}&s=1$

$latex => P = \frac{7803\times 50\times 50}{51\times 51} = 7500Rs&s=1$

Hence option [B] is correct answer.
