Amount of 5 years = 1375 Rs.
Amount of 7 years = 1980 Rs.
Difference = 1980 -1375 = 605
Then
R= 20 %

P= 20,000 t = 5 years , R = 5 %
So the present value
Let this be by Pv
Desired answer = future value ( at the end of 5 years )
Pv (1+5 % ) 5
Pv (1.05)5
Pv x 1.276
= 115920 Rs.

Rate = 10 %
1/10 = 1 increases on 10
In second square on both side given is 2662 but we have -121
So , 2662/121 = 22
Sum borrowed = 210 x 22 = 4620 Rs.

Let if we lent the whole sum at 12 % of interest
Difference B/W origibal and assumed
Is is because of difference in rate of interest
So the sum is lent at 8 % interest

R% = difference amount after n And (n+1) years /amount after n years x 100
%
Let us assume P = 100 then
Total interest when P = 100 is 28.8
3rd year interest given = 1260
Then the common value multiplied = 1260 /28.8 = 43.75
So principal = 43.75 x 100 =4375

Difference between S.I and C.I = 25.60 Rs.
Because B is calculated A at same rate at which A is calculated On P
i.e 8%
so B is 8 % of A , then A
And A is 8 % of p then

test
Option 1) Option 2) Option 3) Option 4) Option 5)

If a sum of Rs.2310 is due to be repaid at the end of two years. If it has to be repaid in two equal annual installments (the installments being paid at the beginning of the year) at 10% p a. compounded annually, Then the value of each installment is:

After 1st year amount
After paid 8000 remaining amount
so clearing loan 22080 Rs. Was paid after 3rd year
