Answer 1

Answer:

$\huge\underline\mathfrak\pink{Answer}$

$\underline\bold\green{give:-}$

$by \: using \: formula = A=P[1+ \frac{R}{100} ]$

$À = P = ₹2400$

$rate \: of \: intrest = 12\%$

$time = t = \frac{5}{2}$

$amount = a$

$A=P[1+ \frac{TR}{100} ]$

$2400(1 + \frac{5 \times 12}{2 \times 100} )$

$2400 \times ( \frac{100 + 60}{200} )$

$24000 \times \frac{160}{200}$

$a = ₹3120$

$according \: to \: the \: problem \: given =$

$1200 + cost \: of \: cow = a$

$cost \: of \: cow = 3120 - 1200 \\ = ₹1920.$

$hence \: the \: cost \: of \: cow \: is \: ₹1920.$
