Question

10. A bank on saving account give compound interest at rate of 8% per annum; but after
six months added the interest in the principal. If Om deposit + 4000, then find the
interest after one year.​

Answer 1

Hear your,

P = 4000

i = 8/100 ×2= 0.04

n =2

Formula of compound interest

= p [(1+i)n -1 ]

= 4000 [ ( 1+0.04)² - 1]

= 4000 [ 1.0816 - 1 ]

= 4000 ( 0.0816 )

= 326.4 rs
