Question

A certain sum amount to 2970.25 in two years at 9% per annum compounded annually. Find the sum.

Answer 1

HeYa mAte heRe iS yoUr aNsWer....
Amont : ₹640
Time period ( n) : 2 years
Rate of interest : 9%

A = P ( 1+R/100)n
2970.25=p ( 1+9/100)²
2970.25=p ( 100+9/100)²
2970.25=p ( 109/100)²
2970.25 = p× 109/100 ×109/100
P = 2970.25 × 100×100/109×109
P = 297025×100×100/109×109
P → ₹2500......

Answer 2

Given Amount = 2970.25, Time n = 2 years, R = 9%.

We know that A = P(1 + r/100)^n

⇒ 2970.25 = P(1 + 9/100)^2

⇒ 2970.25 = P(109/100)^2

⇒ 2970.25 = P(1.1881)

⇒ P = 2500.

Therefore, the sum = 2500.

Hope it helps!
