Question

के बाद रितुको क्या राशि मिलेगी
3) किस दर पर दो वर्षों में ₹ 16000 की राशि ₹ 20000 की
राशि हो जाएगी?
4) कितने समय में कोई धनराशि 10% वार्षिक दर पर दुगनी
धनराशि हो जाएगी​

Answer 1

Answer:

3.

Compound Interest,

Calculate: Rate (R)

Where: r = n[(A/P)1/nt - 1]

Total P+I (A): $ 20,000.00

Principal (P): $ 16,000.00

Compound (n): Compounding Annually (1/Yr)

Time (t in years): 2

Answer:

R = 11.803% per year

Simple Interest,

SI = PRT/100

SI = A - P = 20000 - 16000 = 4000

So,

4000 = 16000*R*2/100

1/4 = R*2/100

R = 50/4 = 12.25 % per year

4.

To Calculate: Time (t)

Where: t = log(A/P) / n[log(1 + r/n)]

Total P+I (A): $ 2.00

Principal (P): $ 1.00

Rate (R): % 10

Compound (n): Compounding Annually (1/Yr)

Answer:

t = 7.273 years

Simple Interest,

SI = PRT/100

SI = A - P = 2-1 = 1

So,

2 = 10*t/100

20 = t year

T = 200
