Question

What is the principal if the simple interest at the rate of 12.5%

for 2 years is `400?​

Answer 1

Answer:

RS. 1600

Step-by-step explanation:

Principal =?

S.I = 400

Time = 2 years

Rate of interest = 12.5%

S.I= p*r*t/100

S.i = p*12.5*2/100

400= 25p/100

40000=25p

p = 1600

The principal is 1600

Answer 2

Answer : 1600

$\rule{100}2$

Given :

• Simple Interest ( SI)= Rs. 400
• Rate (R) = 12.5%
• Time (T) = 2 years

To Find :

• Principal

Formula used :

• $\sf\red{Simple\:Interest} = \dfrac{Principal\times Rate\times Time}{100}$

SolUtion :

First of all, put the given values in the formula.

We get,

$\sf {400}=\dfrac{P\times 12.5\times 2}{100}$

$\sf\implies {P}= \dfrac{400\times 100}{2\times 12.5}$

$\sf\implies {P}\:=400\times 4$

$\sf\therefore P\:=1600$

Hence,

Principal is 1600 for the given S.I.
