Maths chi Assignment Q1.what sum of money put at simple interest for two years at 8% will amount to Rs.1276 ?

Answer 1

Answer:

The sum of money put for simple interest for two years at the rate of $8\%$ p.a.

and which amounts to Rs. $1276$ is Rs. $1100$ .

Step-by-step explanation:

Under simple interest method, we have the formula

$I=PNR/100$  to find the interest.

Here, P is the principal amount

N is the number of years

R is the rate of interest

And the we get the total sum of money by adding the interest to the principal , which is represented by A.

Here given the total money $A=1276$

we have to find the principal .

Since $A= P+I$,

         $1276=P+I$

Let $P=x$,    then

      $I=x(2)(8)/100$

Therefore

          $1276=x+ \frac{16x}{100} \\\\1276= \frac{116x}{100} \\\\x=1276\frac{100}{116} \\\\x=1100$

Therefore the amount invested is Rs. $1100$

Hence the answer
