Question

in what time will₹600 amount to ₹ 672 at the rate of4 percent per annum​

Answer 1

Step-by-step explanation:

amount= 672/-

principle (P)= 600/-

interest (I)= 672-600= 72/-

for simple interest

I= PTR/100

72= 600(4)T/100

T= 72(100)/600×4

T= 3 years

Answer 2

Answer:

$when \: the \: amount \: rup.600$

$and \: the \: increased \: amount \: rup.672$

$so \: the \: interest \: is \: (672 - 600) \: = 72$

$the \: rate \: of \: 4 \: percent \: per \: annum$

$the \: year \: is \: 1 \: year$

$the \: formula \\ \: \: \: \: \: i = \frac{prt}{100} \\ \: \: \:or \: t = \frac{i \times 100}{pr} \\ \: \: \: or \: t = \frac{72 \times 100}{ 600 \times 4} \\ \: \: or \: t = 3 \:$

$so \: answer \: 3 \: years$
