Question

find the compound interest on rs 8000 at 15% for year if the interest is compounded after every four months​

Answer 1

Step-by-step explanation:

P = Rs.8000

R = 15%

T = 1 year

C.I.= P{(1 + ( R/100)^n) - 1}

= 8000{(1 + (15/100)³) - 1}

= 8000{(1 + (3/20)³) - 1}

= 8000{(1 + 27/8000) - 1}

= 8000{((8000 + 27)/8000) - 1}

= 8000{(8027/8000) - 1}

= 8000{(8027 - 8000)/8000}

= 8000 × 27/8000

= 27

Amount = 8000 + 27

= 8027

The compound interest on Rs.8000 at 15% for a year if the interest is compounded after 4 years is Rs.27 and the amount is Rs.8027.

Answer 2

Answer:

C.I. = 8,000 ( ( 1+ 0.15/3)^3 - 1)

= 8,000 ( ( 1.05)^3 -1 )

= 8,000 ( 1.157625 - 1 )

= 8,000 ( 0.157625 )

= ₹ 1,261
