Question

Find the time inyears to earn an interest of RS 500 on RS 2500 at the rate of 5 per annum.

Answer 1

Answer:

$\bigstar\:\boxed{\sf Simple\: Interest=\dfrac{Principal \times Rate \times Time}{100}}$

$\rule{120}{1}$

$\boxed{\bf{\mid{\overline{\underline{\bigstar\:According\:to\:the\:Question :}}}}\mid}$

$:\implies\sf Simple\: Interest=\dfrac{Principal \times Rate \times Time}{100}\\\\\\:\implies\sf Rs.\:500=\dfrac{Rs.\:2500 \times 5 \times Time}{100}\\\\\\:\implies\sf Rs.\:500 = Rs.\:25 \times 5 \times Time\\\\\\:\implies\sf \dfrac{Rs.\:500}{Rs.\:25 \times 5} = Time\\\\\\:\implies\underline{\boxed{\sf Time = 4 \:years}}$

⠀

$\therefore\:\underline{\textsf{Time required in this will be \textbf{4 years}}}.$

Answer 2

SI = 500

principle = 2500

rate = 5per annum

therefore, time = SI×100 by P×R

=500×100 ÷ 2500×5

=4 years

time = 4 years
