Answer:

4 years

Step-by-step explanation:

Simple interest is based on the principal amount of a loan or deposit, whereas compound interest is based on the principal amount and the interest that accumulates on it in every period.

Simple Interest = P x r x n

where P = Principal amount, r = Annual interest rate, n = Term, in years​

6% = 6 ÷ 100 = 0.06  so r = 0.06

Therefore,  

Simple Interest = P x r x n

252 = 1050 x 0.06 x n

252 = 63n

    n = 4

Therefore, he will earn $252 in interest on an initial investment of $1,050 at 6% simple interest over 4 years

Answer:

The time taken in interest is 4 years.

Step-by-step explanation:

As per given question we have provided that :

  • ➣ Interest = $252
  • ➣ Principal = $1050
  • ➣ Rate = 6%

Here's the required formula to find the time:

[tex]{\longrightarrow{\pmb{\tt{I= \dfrac{PRT}{100}}}}}[/tex]

  • ↝ I = Interest
  • ↝ P = Principal
  • ↝ R = Rate
  • ↝ T = Time

Substituting all the given values in the formula to find the Principal :

➠ [tex]{\sf{I= \dfrac{PRT}{100}}}[/tex]

➠ [tex]{\sf{I= \dfrac{P \times R \times T}{100}}}[/tex]

➠ [tex]{\sf{252= \dfrac{1050 \times 6 \times T}{100}}}[/tex]

➠ [tex]{\sf{252= \dfrac{6300 \times T}{100}}}[/tex]

➠ [tex]{\sf{252= \dfrac{63 \cancel{00} \times T}{1 \cancel{00}}}}[/tex]

➠ [tex]{\sf{252 = 63 \times T}}[/tex]

➠ [tex]{\sf{T = \dfrac{252}{63}}}[/tex]

➠ [tex]{\sf{T = \cancel{\dfrac{252}{63}}}}[/tex]

➠ [tex]{\sf{T = 4 \: years}}[/tex]

[tex]\star{\underline{\boxed{\sf{\red{Time = 4 \: years}}}}}[/tex]

Hence, the time taken is 4 years.
