Question

Find the interest and amount in the table given below :

Principal(Rs.)
1600
1000
2000
4000
8000

Rate of Interest(R)
8*1/3%
10%
7*1/2%
12.5%
13*1/2%

I=PRN/100(Rs)
I=1600*25*45/100*3*10

Amount A=P+I(Rs)
A=1600 +600 A=2200

Answer 1

Answer:

I = 600 , A = 2200

I = 450 , A = 1450

I = 675 , A = 2675

I = 2250 , A = 6250

I = 4860 , A = 12860

Step-by-step explanation:

Since the principal , rate and time is given in the table.

We have to find the Interest and amount of the each data given in the table.

Since Interest is given by I = $\frac{PRINCIPAL \times RATE \times TIME}{100}$

Amount is given by (A) = P + I

For, principal =  1600    and  Rate = 25/3 %

We get I =  I = $\frac{1600 \times 25/3 \times 45/10}{100}$

I = 600

Since Amount (A) =  I+P

= 600 + 1600=2200

A=2200

For, principal =  1000    and  Rate = 10 %

We get I =  I = $\frac{1000 \times 10 \times 45/10}{100}$

I = 450

Since Amount (A) =  I+P = 450 + 1000 = 1450

For, principal =  2000    and  Rate = 15/2 %

We get I =  I = $\frac{2000 \times 15/2 \times 45/10}{100}$

I = 675

Since Amount (A) =  I+P = 675 + 2000 = 2675

For, principal =  4000    and  Rate = 12.5 %

We get I =  I = $\frac{4000 \times 12.5 \times 45/10}{100}$

I = 2250

Since Amount (A) =  I+P = 2250 + 4000 = 6250

For, principal =  8000    and  Rate = 27/2 %

We get I =  I = $\frac{8000 \times 27/2 \times 45/10}{100}$

I = 4860

Since Amount (A) =  I+P = 4860 + 8000 = 12860

Answer 2

I = Rs. 600 , A = Rs. 2200

I = Rs. 450 , A = Rs. 1450

I = Rs. 675 , A = Rs. 2675

I = Rs. 2250 , A = Rs. 6250

I = Rs. 4860 , A = Rs. 12860

Step-by-step explanation:

Principal and Rate of interest are given. Time, we get from the first working as 45/10.

Formula used:  

Interest = PNR/100 = Principal * Time * Rate / 100

Amount = Principal + Interest.

Let's substitute the values to solve the 5 questions.  

1) Principal =  1600;  Rate = 25/3 % ; N = 45/10

   We get I = 600 and Amount = 2200

2) Principal =  1000 ;  Rate = 10 % ; N = 45/10

    We get I = 450 and Amount = 1450

3) Principal =  2000 ; Rate = 15/2 % ; N = 45 /10

   We get I = 675 and Amount = 2675

4) Principal =  4000 ; Rate = 12.5 % ; N = 45 / 10

    We get I = 2250 and Amount = 6250

5) Principal =  8000 ;  Rate = 27/2 %  ; N = 45 / 10

    We get I = 4860 and Amount = 12860
