according to first statement :

-----------------------------------------

principal = Rs 20000 , rate = 12% ,

time = 2 yrs, since we know that ,

S.I = p × r × t / 100

=20000 × 12 × 2 / 100 = Rs 4800

Amount harish has return to his friend at simple interest

A1 = 20000 + 4800 = Rs 24800

according to second statement:

----------------------------------------------

he lent it to amit at the same rate of interest and time but compounded annually.

p = 20000, t = 2 yrs , r = 12 %

Find the Amount :

--------------------------

amount = p [ 1 + ( r/100) ]^t

=20000 [ 1 + ( 12 / 100 ) ]^2

=20000 ( 112/ 100 )^2

=20000× (112/ 100 ) × ( 112/100 )

=25088

A2 = 25088

Find the gain :

--------------------

gain = A2 - A1 = 25088 - 24,800

gain = Rs 288

therefore ,

his gain after 2 years = Rs 288

Answer : gain = Rs 288
