Answer 2

Answer:

Rate = 10%

Given:-

• principle = 32000
• number of year time = 2
• Amount = 38400
• R = ?

To find :-

• rate of interest

Solution:-

Here,

we will solve through simple ineterst

$as \: we \: know \\ \\ amount \: = principle \: + simple \: interst \\ \\ 38400 = 32000 - s.i \\ \\ s.i = 38400 - 32000 \\ \\ s.i = 6400$

now,

$s.i = \frac{p \times n \times r}{100} \\ \\ 6400 = \frac{32000 \times 2 \times r}{100} \\ \\ \frac{6400}{320 \times 2} = r \\ \\ rate \: = 10\%$
