A) Rs.6000/- B) Rs.6500/- C) Rs.7000/- D) Rs.7200/- E) Rs.8000/-
principal P = ?   Rate of interest R = 10%   Time T = 3 years   Accumulated Amount A = Rs.10400/-   A = P + I   A = P + PTR/100   A = P(1+ TR/100)   Rs.10400/- = P [1 + 3*10/100]   Rs.10400/- = P [1/1 + 3/10]   Rs.10400/- = P [10+3/10] = P[13/10]   Rs.10400/- = P * 13/10   ==&gt; P = Rs.104000/13   ==&gt; P = Rs.8000/-   Rs.8000/-
