A.) Rs.7000/- B.) Rs.8000/- C.) Rs.9000/- D.) Rs.1000/- Answer: Option 'B'

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

==> P = Rs.104000/13

==> P = Rs.8000/-
