If the principal be Rs. `p` and the annual rate of interest be `r_(1)%` in the 1st year `r_(2)%` in the 2nd years, then write the amount after `n` years.

If the principal be Rs. p and the annual rate of compound interest be r% and if interest is compunded at the end of a year, then write the amount after 3 1/4 years.

If the principal be Rs. p and the annual rate of compound interest be r% then write the amount after n years when interest is compounded at the interval of 3 months.

Let P be the principal and the rate of interest be R_1 % for first year R_2 % for second year R_3 % for third year and so on and in the last R_n % for the nth year. Then the amount A and the compound interest C.I. at the end of n years are given by A=P(1+R_1/100) (1+ R_2/100) ...... (1+ R_n/100) and C.I. =A-P respectively.

If the annual rate of compound interesting 1st year be r_(1)% , in 2nd year be r_(2)% and in 3rd year be r_(3)% then the total amount of principal Rs. p in 3 years =

The annual rate of compound interest in 1st year be r_1% , in 2nd year be r_2% and the 3rd year be r_3% , then the total amount of principal ₹ p in 3 years =

Find the amount of Rs 50000 after 2 years, compounded annally, the rate of interest being 8% p.a. during the first year and 9% p.a. during the second year. Also, find the compound interest.

A. Write true of false: a. If Principal =Rs.p , rate of compound interest per annum =r% and time =n years, then the amount after 2 years is Rs. p(1+r/100)^(2) b. If principal =Rs. p and rate of compound interest per annum for first, 2nd and 3rd year be r_(1)%, r_(2)% and r_(3)% respectively, then total amount for 3 years. =Rs. p(1+(r_(1))/100)^(3)+Rs. p(1+(r_(2))/100)^(3)+Rs. p(1+(r_(3))/100)^(3)

If the rate of compound interest for the first year is 4% and 2nd year is 5% where compound interest on Rs. 25000 for 2 years is

If the rate of compound interet for the 1st and 2nd year are 4% and 5% respectively, then find the compound interest on Rs 25,000 for 2 years.
