Question

1. Find the simple interest and the amount. a. P= ₹1800 , R = 5% T= 1 year​

Answer 1

Answer:

I = PRT/100 = 1800 x 5 x 1 /100 = 18 x 5 = 90

A = 1800+90=1890

Answer 2

To find : simple interest and amount

Given : P = ₹$1800$   , R = $5\ \%$   , T = $1$ year

• We know that , the simple Interest of an amount is calculated by multiplying the interest rate by the principal amount and the time period. the time period in years.
• $SI = \frac{P\times R\times T}{100}$

• Where ,  P = Principal Amount , T = Time in Years   , R = Rate of Interest   per Annum.

     $SI =\frac{1800\times 5\times 1}{100}$

          $= 18\times 5\times 1 \\= 90$  

• Hence , SI is $90$ Rs .
• Amount = S.I + principal amount  

                      $= 90 + 1800 \\= 1890$

    Hence, the S.I is $90$ Rs  and amount is $1890$ Rs .
