Calculate the compound interest for the third year on $$Rs.\ 7,500$$ invested for $$5$$ years at $$10\%$$ per annum.

The value of a machine depreciated by $$10 \%$$ per year during the first two years and $$15 \%$$ per year during the third year. Express the total depreciation of the machine, as per cent, during the three years.

Calculate the amount and the compound interest on Rs. $$6,000$$ in $$3$$ years at $$5\%$$ per year.

Calculate the amount and the compound interest on Rs. $$16,000$$ in $$3$$ years, when the rates of the interest for successive years are $$10\%$$, $$14\%$$ and $$15\%$$ respectively.

The value of an article which was purchased $$2$$ years ago, depreciates at $$12$$ % per annum. If its present value is Rs .$$ 9680$$, the price at which it was purchased is:

Mohan lent some amount of money at $$9\%$$ simple interest and an equal amount of money at $$10\%$$ simple interest each for $$2$$ years. If his total interest was Rs. $$760$$, what amount was lent in each case?

Arun borrowed a sum of money from Jayant at the rate of $$8\%$$ simple interest for the first four years, $$10\%$$ p.a. for the next $$6$$ years and $$12\%$$ p.a. beyond $$10$$ years. If he pays a total of Rs. $$12160$$ as interest only at the end of $$15$$ years, how much money did he borrow?

A person lent a certain sum of money at $$4\%$$ simple interest and in $$5$$ years, the interest amounted to Rs. $$520$$ less than the sum lent. The sum lent was

The cost of a vehicle is Rs. $$1,75,000$$. If its value depreciates at the rate of $$20$$ % per annum, then the total depreciation after $$3$$ years will be:
