Answer 2

Correct question:

Find simple interest and the amount on 4000rs at a rate of interest per annum 5% for 6months?

To find:

$\to$The simple interest

$\to$The amount

Given:

• Principle=4000rs
• Rate of interest per annum=5%
• Time=6 months

Solution:

$\to$6 months = $\frac{1}{2}$ years

→Simple interest formula:

Simple interest=$\frac{Principle*Rateofinterestper annum*Time}{100}$

Let,Simple interest be SI rs

Finding the simple interest by its formula,

$\to$ SI =$\frac{4000*\frac{1}{2}*5 }{100}$

$\to$ $or,$ SI =$\frac{4000}{1} *\frac{1}{2} *\frac{5}{1} *\frac{1}{100}$

$\to or,$ SI = $100$

→Formula of amount:

Amount=(Principle + Simple interest)

Therefore,

The amount=(4000 + 100 )rs

                   =4100rs

Verification:

$\to 100 = \frac{4000*5*\frac{1}{2} }{100}$

$\to or,100=\frac{4000}{1} *\frac{1}{2} *\frac{5}{1} *\frac{1}{100}$

$\to or,100=100$

Therefore,L.H.S=R.H.S

Hence,Verified

Answer:

The simple interest = $100$ rs

The amount = $4100$ rs
