Question

principal= 1670 rate =10% time=? Interest =417.50​

Answer 1

Step-by-step explanation:

Equation:

t = I / Pr

Calculation:

First, converting R percent to r a decimal

r = R/100 = 10%/100 = 0.1 per year,

then, solving our equation

t = 417.5 / ( 1670 × 0.1 ) = 2.5

t = 2.5 years

The time required to

accumulate simple interest of $ 417.50

from a principal of $ 1,670.00

at an interest rate of 10% per year

is 2.5 years (about 2 years 6 months

Answer 2

$\Large{\underline{\underline{\mathfrak{\tt{\red{Question}}}}}}$

principal= 1670, rate =10%, time=? ,Interest =417.50

$\Large{\underline{\underline{\mathfrak{\tt{\orange{Solution}}}}}}$

$\Large{\underline{\mathfrak{\tt{\red{Given}}}}}$

$:\mapsto\tt{\green{\:Principal(P)\:=\:1670\:Rs}} \\ \\ :\mapsto\tt{\green{\:Rate(R)\:=\:10\%}} \\ \\ :\mapsto\tt{\green{\:Interest(S.I.)\:=\:417.50\:Rs.}}$

$\Large{\underline{\mathfrak{\tt{\red{Find}}}}}$

$:\mapsto\tt{\blue{\:Time(T)}}$

$\Large{\underline{\underline{\mathfrak{\tt{\red{Explanation}}}}}}$

Important Formula

$\boxed{\tt{\orange{\:S.I.\:=\:\dfrac{(P\times R\times T)}{100}}}}$

Keep all values ,

$:\mapsto\tt{\:417.50\:=\:\dfrac{(1670\times 10\times T)}{100}} \\ \\ :\mapsto\tt{\:417.50\:=\:167\times T} \\ \\ :\mapsto\tt{\:T\:=\:\cancel{\dfrac{417.50}{167}}} \\ \\ :\mapsto\tt{\orange{\:T\:=\:2.5\:years}}$

Hence

$:\mapsto\tt{\blue{\:Time\:be\:=\:2.5\:years}}$
