Question

if the simple interest on a sum of 4%per annum for 2 years is ₹80 then the compound interest on the same sum for the same period is​

Answer 1

Answer:

81.6 rupees

Step-by-step explanation:

( * ) means multiplication sign (asterisk *)

take x as principal

p = x

N = 2

R = 4

SI = (PNR/100)

SI = (x*2*4/100)

=>  x = 80×100/4×2

=>  x = 1000

NOW TO FIND CI

=[1000(1+4/100)*2]

=1000 * 26/25 * 26/25

=1081.6

NOW

CI = 1081.6 subtracting from principal

= 1081.6 - 1000

= 81.6

HOPE THIS HELPS YOU :)
