Question

find amount for rs 10000 rate 5% and time 2 1/2 years compounded half yearly​

Answer 1

Answer:

p= 10000

r = 5%

t = 2 1/2 years

Here P=10,000 Rs.,

n=2(2 1/2)

=3 years(Compounded semi-annually) and

R= 5/2

(Compounded semi-annually)

Amount(A)=P(1+R/100 ) ^n

=5000(1+ 5/2×100 ) ^3

=5000(40/41 ) ^3

= 40×40×40/(41) ^3 × 5000

=10,768.90 Rs.

Compound interest(C.I)=

A−P=10,768.90−10,000=768.90

Hence, the compound interest is Rs. 769.
