1. Answer:

   As per given question,

   Amount for the first year:

   A=P(1+

   100

   R

   )

   n

   =40000(1+8/100)

   1

   =40000×108/100=Rs. 43200

   Now, amount for the second year:

   A=P(1+

   100

   R

   )

   n

   =43200(1+8/100)

   1

   =43200×108/100=Rs. 46656

   Compound interest =Amount−Principle

   Rs. 46656−Rs. 43200=Rs. 3456

2. Answer:

   A=P(1+r/100)^t

   =40000(1+8/100)²

   =40000(108/100×108/100)

   =4×108×108

   =46656

   C.I=A-P

   =46656-40000

   =6655,is your answer
