Answer:

Step-by-step explanation:

12. Shanta borrowed 6000 from the State Bank of todia for years

annum. What amount will clear off her debu?

Given principal = 6000 Rs

Time = 3 years 8 month =  

3

11

​  

 years.

Rate = 12% per annum

We know simple interest =  

100

PRT

​  

 

SI=  

100

6000×12

​  

×  

3

11

​  

 

SI=24×11=2640

SI=2640Rs

Now amount = principal + SI

= 6000+2640

[ amount = 8640 Rs]

∴ 8640 Rs is that amount which will clear off her debt.

3.Hari borrowed 19600 from a moneytender at 15% per annum

ans:3 years, he paid 7070 and gave a goat to clear of the debt What

SI = P * R * N/100  

=12600*3*15/100  

=126*3*15  

=5670  

Interest = 5670 + Principal 12600=17670  

He repaid Rs. 7070  

cost of goat = 17670-7070= Rs. 10,600

14. The simple interest on a certain sum for 3 years al 10% per annumis 20.0

ans:

let the sum = principal =P

time =T= 3 yrs

rate of interest = R= 10%

simple interest =I= 829.50

15. A sum when reckoned at 7% per annum amount to 8020 in 3 years

ans:I = PTR/100

P = (100*I)/(TR)

P =(100*829.50)/(3*10)

=82950/30

=Rs2765

Principal = P = Rs 2765

A= 3920

T=3

R=15/2%

Let the P be 100

(100X3X15) /(100X2)= 22.5

A=(100+22.5)=122.5

If A=122.5, P=100

If A=3920, P=(100/122.5)X 3920

=3200

The principal is 3200

16. A sum of money put at 11% per annum amounts to 4401 in 9 years Ab

amount to in 3 years at the same rate

Question

A sum of money put at 11% per annum amounts to Rs 4491 in 2 years 3 months. What will it amount to in 3 years at the same rate?

Given:-

Amount = Rs.4491

Time = 2 years 3 months

Interest = 11%

To Find:-

Amount (at the end of 3 years) = ?

Solution:-

Let Principle money = x

We know simple interest  

Here,

Interest = ( 4491 - x ) rs

Rate ( R ) = 11%

time ( T )= 2 +

= 2.25 years.

So,

4491 -  

449100 - 100x = 24.75x

124.75x = 449100

x = 3600

So he has sum of money in starting is = 3600 Rs.

Now he gets after three year

here P = 3600 , R = 11% And T = 3years

Interest  

Interest = 1188 Rs

So total amount will be = 3600 + 1188 = 4788 Rs
