Question

At what rate percent per annum will Rs 1625 amount to Rs 2080 in 3 1/2 ℅.

Answer 1

$\huge\bold{Solution}$

$<b><i><u>$ We use Rate percent formula

I* A / P* 100

A =p+ I

I = A - P

I = 2080- 1625

I= 455

T =
$3 \times \frac{1}{2} \\ = \frac{7}{2}$
455 * 100 / 1625* 7/2

= 45500/ 5687.5

Rate = 8%

$\huge\bold{ Rate = 8%}$
