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 =

Ganesh bought a refrigerator for Rs. 30000 in credit. If the rate of compound interest is the 1st year be 5%. In the 2nd year be 10% and in the 3rd year be 15%, then find the total amount he would have to pay after 3 years.

If the rate of compound interest for the first year be 3%, for the second year be 2% and for the third year be 1% then find the sum of the money, the amount of which of 3 years is Rs. 15916.59.

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.

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 principal =Rs. p and rate of compound interest per annum for first, 2nd and 3rd year are r_(1)%, r_(2)% and r_(3)% respectively, then find total amount for first year.

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.

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
