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

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
