Question

find the compound intrest and amount if the principal is 2000, rate is 5 and and duration 2 years​

Answer 1

principal=₹2000

rate=5%

Time=2 years

formula of Si is p×r×t÷100

=2000×5%×2÷100

=₹200

amount= principal+simple interest

a=2000+200

=₹2200

Answer 2

Solution :-

Given :
Principal = p = ₹2000
Rate = r = 5% ,
Time = t = 2 years

Find the Amount (A) :-

A = p(1 + r)^t
A = 2000(1 + 5%)²
A = 2000(1 + 0.05 )²
A = 2000(1.05)²
A = 2000 × 1.1025
A = 2205

Find the compound interest (C.I) :-

C.I = A - p
C.I = 2205 - 2000
C.I = 205

Hence,
Amount = ₹ 2205
Compound Interest = ₹ 205
