Answer 1

Answer:

1) Rs 172.80

Step-by-step explanation:

P=12000, R=12%, n=2

For Cl

A=P(1+R/100)ⁿ

=12000(1+12/100)²=12000(1.12)²=12000(1.2544)

= 15052.80

CI=A-P=15052.80-12000= 3052.80

For SI

SI=PRN/100

=12000×12×2/100

= 2880.00

Difference between CI and SI = 3052.80-2880.00

= Rs 172.80
