mel-nik [20]

Answer:

Amount = p( 1+r/100) ^n

= 12000 ( 1+10/100) ²

= 12000( 10/10+1/10) ²

= 12000( 11/10) ²

= 12000 x 11/10 x 11/10

= 14520 rs.

Compund interest = amount - principal

= 14520 - 12000

= 2520rs.

How can you be sure that 0.56 ÷ 100 = 0.0056 ?
denis-greek [22]
For every factor 10, move the decimal point one position. Pad with zeros where necessary. Dividing moves to the left, multiplication to the right.

So dividing by 100 is moving it 2 places to the left.
