#### If the difference between compound interest at 8% p.a. and simple interest at 13/2 % p.a. on a certain sum of money for 2 years is Rs. 1820, then find the sum. Option 1) Rs. 50000         Option 2) Rs. 22000      Option 3)  Rs.32000Option 4)  Rs.25000 Option 5) Rs. 40000

Difference between C.I and S.I = 1820

#### A sum of money compounded annually amounts to Rs.1375 in 5 years and Rs.1980 in 7 years. Find the annual rate of interest   Option 1)   12%              Option 2)    20%                       Option 3)   11%   Option 4)    10%   Option 5)   15%

Amount of 5 years = 1375 Rs.

Amount of  7 years = 1980 Rs.

Difference = 1980 -1375 = 605

#### A man saves Rs.20000 at the beginning of each year and puts the money in a bank that pays 5% interest per year, interest being compounded annually. How much would be the total savings of the man at the end of 5 years? (Given that (1.05)5 = 1.276) Option 1) Rs. 115920                Option 2)  Rs.125570           Option 3)  Rs.140460        Option 4)  Rs.134460     Option 5)  None of these

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.

#### A loan is taken today and repaid in two annual instalments (paid at the end of the year) of Rs.2662 each. The rate of interest is 10% p.a and it is compounded annually. Find the sum borrowed. Option 1) Rs.4540                        Option 2)  Rs 4620               Option 3) Rs.4520  Option 4)  Rs.2152 Option 5)  Rs.2848

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.

#### A man borrowed Rs.55000 from two banks under compound interest, compounded annually. One bank charged interest at the rate of 8% per year and the other bank at 12% per year. If at the end of the year the man paid Rs.4900 as the total interest to the two banks, how much loan did he take from the first bank?   Option 1)   Rs.47500   Option 2)   Rs.42500   Option 3)   Rs.32500   Option 4)   Rs.45200   Option 5)   Rs.12500

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

#### A certain sum, at compound interest, yields Rs. 1260 and Rs.1512 for the third and fourth years respectively. Find the sum Option 1) Rs.4500         Option 2)    Rs.4375       Option 3)   Rs.4800   Option 4) Rs 4425Option 5) Rs.4650

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
