Question

Calculate the interest on rs7000 for 2 years at the rate of 8% per annum when the interest is compound annualy?

Answer 1

==================================

$\underline\bold{\huge{SOLUTION \: :}}$

==================================

GIVEN INFORMATIONS :

(1) P = Rs. 7000
(2) n = 2 years
(3) r = 8%.


BY USING FORMULA,


C. I. = P [(1+r/100)^n - 1]

=> C. I. = 7000 [(1+8/100)²-1]

=> C. I. = 7000 [(27/25)² - 1]

=> C. I. = 7000 [(729/625)-1]

=> C. I. = 7000 × (104/625)

=> C. I. = 1164.80

==================================

SO, THE COMPOUND INTEREST ON Rs. 7000 FOR 2 YEARS AT 8% PER ANNUM IS Rs. 1164.80$\bold{[ANSWER]}$

Answer 2

GIVEN INFORMATIONS : 

(1) P = Rs. 7000
(2) n = 2 years
(3) r = 8%. 


BY USING FORMULA, 


C. I. = P [(1+r/100)^n - 1]

=> C. I. = 7000 [(1+8/100)²-1]

=> C. I. = 7000 [(27/25)² - 1]

=> C. I. = 7000 [(729/625)-1]

=> C. I. = 7000 × (104/625)

=> C. I. = 1164.80 [ANS.]
