Question

the compound intrest on a certain sum of money at 5% p.a for 2 years is 246 . calculate the simple intrest on the sum for 3 years at 6% p.a .​

Answer 1

Answer:

S.I = Rs.432

Step-by-step explanation:

CI = 246

R = 5%

T = 2 yrs                                                        (GIVEN)

  CI = A-P

246 = P[1+5/100]^2 - P

246 = P[(21/20)^2 - 1

246 = P[61/400]

P = 246*400 / 41  

  = Rs. 2400

     Now, P = 2400 , R = 6% , T = 3yrs                  (rate and time was given)

SI = 2400 * 6 * 3 / 100  

    = 432

  HOPE THIS WAS HELPFUL...
