Question

find the amount to be paid at the end of 1 year on rs 1800 at 8% per annum compounded semi - annually

Answer 1

S.I = p*T*r/100
        1800*1*8
      =  144

Amount = p+ S.I
             =  1800+144
             = rs. 1944

Answer 2

first we'll find simple interest by using formula
SI=
$\frac{p \times r \times t}{100}$
$\frac{1800 \times 8 \times 1}{100}$
=144
now, amount=principal+simple interest
=1800+144
=1944/-
