u are suppose to find the pricipal first...so
a = p (1+r/100)n
40000 = p (1+10/100)3
40000 = p (11/10)3
p = 40000×11/10×11/10×11/10
p =53240
then compound interest = a - p
40000 - 53240
i.e 13240
a = p (1+r/100)n
40000 = p (1+10/100)3
40000 = p (11/10)3
p = 40000×11/10×11/10×11/10
p =53240
then compound interest = a - p
40000 - 53240
i.e 13240
