15P = 60000

P = 4000

Answer 2

$\huge\mathfrak\red{☟ \: \: \: answer \: \: \: ✎}$

$⇒ Here, we have \: \: T=3 \: years,R=5%$

$and \: S.I.=Rs. \: 600$

$⇒S.I = \frac{p \times r \times t}{100}$

$⇒600 = \frac{p \times 5 \times 3}{100}$

$⇒ \frac{600 \times 100}{5 \times 3} = Rs. \: 4000$

$⇒now \: taking \: P = Rs. \: 4000$

$T = 3 \: years \: and \: R = 5\%$

$⇒ A = P ( 1 + \frac{R}{100} {)}^{T}$

$⇒ A = 4000 \times (1 + \frac{5}{100} {)}^{3}$

$⇒ A = 4000 \times ( \frac{21}{20} {)}^{3}$

$⇒ A = \frac{4000 \times 9261}{8000} = Rs. \: 4,630.50$

: The Required Amount is Rs. 4,630.50
