Question

A, b and c are such that b is the simple interest on a and c is the simple interest on b for the same period and same rate of interest. the relation between these three is ___

Answer 1

Answer:

b^2 = a * c

Step-by-step explanation:

Formula for simple interest SI = PNR/100

Principal amount (P) = a

N is no.of years.

R is Rate of interest.

In first case, SI = b

So,

b = a * N * R / 100

NR/100 = b/a

In second case, SI = c

Values of N and R are same in both cases.

Therefore,

c = b * NR / 100

c = b * b/a

Therefore,

b^2 = ac
