Question

write equation for finding interest​

Answer 1

Answer:

Use this simple interest calculator to find A, the Final Investment Value, using the simple interest formula: A = P(1 + rt) where P is the Principal amount of money to be invested at an Interest Rate R% per period for t Number of Time Periods. Where r is in decimal form; r=R/100; r and t are in the same units of time.

Answer 2

Step-by-step explanation:

$\huge{\underline{\mathrm{Question}}}$

⠀━━━━━━━━━━━━━━━━━━━━━━━━

Calculate the Simple Interest if the principal amount is Rs. 2000, the time period is 1 year and the rate is 10%. Also, calculate the total amount at the end of 1 year.

⠀━━━━━━━━━━━━━━━━━━━━━━━━

$\huge{\underline{\mathrm{Solution:}}}$

According to the formula of simple interest we have,

$SI = \frac{(P) \times (T) \times (R)}{100 } \\ \\ = SI = \frac{(2000 - \times 1 \times 10)}{100} \\ \\ = \frac{20000}{100} \\ \\ = 2000$

So, the simple interest at the end of 1 year will be Rs. 200.

For the amount after 1 year,

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⇛⠀A = P + S.I.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⇛ A = 2000+200

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⇛ 2200

Hence, the total amount at the end of the given tenure (i.e. 1 year) will be Rs. 2200.
