Answer 1

$\huge\underline\blue{\sf Given:}$

P = 12500

T = 4 years

A = 15500

Question :--- R = ?

Solution :----

$si = amount - principal \\ \\ si = 15500 - 12500 \\ \\ si = 3000rs$

Now, We know That ,

$rate\% = \frac{si \times 100}{p \times t} \\ \\ r\% = \frac{3000 \times 100}{12500 \times 4}$

$\huge\blue{Rate\:=6%}$
