Answer 2

Given:

Years=2

Rate=8% p.a.

Amount=1276

To find:

The principal sum

Solution:

The required sum is Rs.1100.

We have the given amount that is inclusive of the principal.

So, to obtain the interest, we will have to deduct the principal from the interest.

Let the required sum be P.

The interest amount=Amount-principal

Using values,

Interest=1276-P

Also, interest=Principal sum×rate×years/100

So, interest amount=P×8×2/100

On equating, we get

1276-P=16P/100

1276=P+16P/100

1276=(100P+16P)/100

1276=116P/100

1276×100/116=P

1100=P

Therefore, the required sum is Rs.1100.
