Q:

If J is the interest on K and K is the interest on L, the rate and time is the same on both the cases. What is the relation between J, K and L  ?

 A) JxJ = KL B) KxK= JL C) LxL = JK D) JKL = 1

Explanation:

Let the Time be 'N' and Rate be 'R'

J = (K x NR)/100 K = (L x NR)/100

J/K = NR/100 K/L = NR/100

J/K = K/L

$\inline \fn_jvn K^{2}$ = JL
