Question

find the principal when : S.I = 980 Rate= 8% Time=7/2  years​

Answer 1

si = ptr/100

980 = p×7/2×8/100 =28/100 ×p

14000/4 = p

7000/2 =p

p =3500

Answer 2

Answer:

The Principal is 3500.

Step-by-step explanation:

In context to the question asked,

We have to find the value of the principal,

As per data given in the question,

We have,

Simple interest ( S.I ) = 980

Rate ( R ) = 8%

Time ( T ) = $\frac{7}{2}$ years

As we know that,

$S.I = \frac{P\times R \times T }{100}$

Substituting the given values,

$=> 980 = \frac{P\times 8 \times \frac{7}{2} }{100}$

Simplifying it further, we get

$=> 980 = \frac{P\times 8 \times7 }{100\times 2}$

$=> 980 = \frac{56}{200}\times P$

$=> 980\times 200 = 56\times P$

Multiplying the numbers,

$=> 196000 = 56\times P$

Divide 196000 by 56,

$=> \frac{196000}{56}=P$

$=> 3500=P$

Hence, the required principal is 3500.
