Answer 1

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

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

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

GIVEN INFORMATIONS :-

(1) P = Rs. 40,000

(2) r = 12% = (12/4)% = 3% (quarterly)

(3) n = 9 months = (9/3) or 3 quarters.

BY USING FORMULA, WE GET :

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

=> C. I. = 40000 [(1+3/100)³ - 1]

=> C. I. = 40000 [(1092727/1000000)-1]

=> C. I. = 40000 (92727/1000000)

=> C. I. = ₹ 3709.08

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

THUS THE COMPOUND INTEREST ON RS. 40,000 FOR 9 MONTHS AT THE RATE OF 12% PER ANNUM (COMPOUNDED QUARTERLY) IS RS. 3709.08 $\bold{[ANSWER]}$

Answer 2

$\bold{Hi \: There!}$..❤

P = Rs. 40,000

R = 12% = (12/4)% = 3% (quarterly) 

N = 9 months = (9/3) or 3 quarters. 

BY USING FORMULA, WE GET :

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

=> C. I. = 40000 [(1+3/100)³ - 1]

=> C. I. = 40000 [(1092727/1000000)-1]

=> C. I. = 40000 (92727/1000000)

=> C. I. = ₹ 3709.08
