solve with ans : the compound interest of a sum of money in 1 years and 2 years are Rs 450 and Rs 945 respectively. find the rate of interest compounded yearly and the sum .

Step-by-step explanation:

Compound Interest Formula, Amount,

Interest=Amount - Principal

At the end of 1 year, interest =Rs450, therefore:

At the end of 2 years, interest =Rs945, therefore:

Recall: Pr=450

Therefore:

Comparing Pr=450 and

Substitute r=0.1 to obtain P

0.1P=450

P=Rs4500

Therefore:

the answer

b. they are parallel and will never intersect.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
