Question

Find Time when principal rs 6400 simple interst rs1908 and rate 8%​

Answer 1

Answer:

4 years

Step-by-step explanation:

Simple Interest (SI) = Rs.1908

Principal (P) = Rs.6400

Rate (R) = 8%

SI = PRT/100

=> 1908 = 6400×8×T/100

=> T = 1908/512

=> T = 4 years

Answer 2

Given :

• Principal is Rs.6400 , Simple Interest is Rs.1908 and Rate of Interest is 8% .

To Find :

• Time .

Solution :

$\longmapsto\tt{Principal(P)=Rs.6400}$

$\longmapsto\tt{Simple\:Interest(S.I)=Rs.1908}$

$\longmapsto\tt{Rate\:of\:Interest=8\%}$

Using Formula :

$\longmapsto\tt\boxed{Simple\:Interest=\dfrac{P\times{R}\times{T}}{100}}$

Putting Values :

$\longmapsto\tt{1908\dfrac{6400\times{8}\times{T}}{100}}$

$\longmapsto\tt{1908=\dfrac{51200\:T}{100}}$

$\longmapsto\tt{1908\times{100}=51200\:T}$

$\longmapsto\tt{T=\dfrac{1908{\not{0}}{\not{0}}}{512{\not{0}}{\not{0}}}}$

$\longmapsto\tt{\cancel\dfrac{1908}{512}}$

$\longmapsto\tt\bf{3.72\:yrs.}$

So , The Time is 3.72 years ..

• Amount = Principal + Interest
• Principal = Amount - Interest
• Simple Interest = P×R×T / 100
• Profit = S.P - C.P
• Loss = C.P - S.P
• Profit % = Profit × 100 / C.P
• Loss % = Loss × 100 / C.P
