Question

Find the sum if simple intrest at a% per annum for 'a' year is rs 'a'

Answer 1

We know the formula:

I = Ptr/100, where P = sum

I = interest

t = time

r = rate of interest

Given:

• I = a
• t = a
• r = a% p.a.

To find: the sum, P = ?

Putting values in above formula, we get

a = P * a * a / 100

or, P = 100/a

Therefore the sum is 100/a.

Answer 2

Answer:

100 / a

Step-by-step explanation:

p = si × 100 / rate × time

p = a × 100 / a × a

p = 100 / a
