10%

• Option 5)

15%

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

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 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
Rate of interest 8% for 2 years = 16 % 10 % for 3 years = 30 % 5 % for 2 years = 10 % 7 % for 1 year = 7 % Amount = 163% of P

A certain sum, at compound interest, yields Rs. 1260 and Rs.1512 for the third and fourth years respectively. Find the sum

Rs 4425

• Option 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
By solving this we get R = 13.55 %
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
