Question

कोई राशि चक्रवृद्धि ब्याज की दर से 2 वर्ष में ₹882 तथा 3 वर्ष में 926.10 हो जाती है तो वह राशि तथा दर ज्ञात करें​

Answer 1

Answer:

Amount =800

rate=5%

Step-by-step explanation:

amount in 2 years =882

amount in 3 years =926.10

Now

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

882=p(100+r)/100)^2. (1)

similarly

926.10=p(100+r)/100)^3. (2)

devide (2) by (1)

926.1/882=1+r/100

926.1/882=100+r)/100

926.1*100=88200+882r

92610=88200+882r

882r=4410

r=4410/882=5%

And

again according to question

882=p(1+ r/100)²

882=p(1+ 5/100)²

882=p*105/100x105/100

882=p441/400

p=882*400/441=800

Amount =800
