Question

find the amount and compound interest on rupees 3500 at 20 % for 3 years​

Answer 1

Step-by-step explanation:

ANSWER

For ,

N=2years

R=10 %

=>P=Rs3,500

And on interest being compounded we have,

Amount=P(1+ R upon 100) raised to n

=3,500×(1+ 10 / 100) sqaure

=3,500×1.1 sqaure

=Rs4,235

So, C.I.=A−P=

Rs4,235 - Rs3,500 =Rs735

Answer 2

To Find :-

• It's Amount and Compound interest.

Solution :-

Given,

• Principal (P) = Rs. 3500
• Rate of interest (R) = 20%
• Time (n) = 3 years

[ First find out Amount ]

We know that,

• A = P(1 + R/100)^n

[ Put the values ]

↪ A = 3500(1 + 20/100)³

↪ A = 3500(100 + 20/100)³

↪ A = 3500(120/100)³

↪ A = 3500(12/10)²

↪ A = 3500 × 12/10 × 12/10 × 12/10

↪ A = 35 × 12 × 12 × 1.2

↪ A = 420 × 14.4

↪ A = Rs.6048

[ Now, find compound interest ]

Let compound interest be "R".

As we know that,

• Compound interest = Amount - Principal

[ Put the values ]

↪ R = Rs (6048 - 3500)

↪ R = Rs.2548

Therefore,

The amount and compound interest is Rs.6048 and Rs.2548 respectively.
