Choose the most appropriate option.
A) Rs. 400	B) Rs. 300	C) Rs. 500	D) Rs. 350	E) None of these
Explanation :   T = 3 years   R = 10%   TD = (BG ×100)/TR = (36×100)/(3×10) = 12 × 10 = Rs. 120   TD = (PW × TR)/100   ⇒ 120 = (PW ×3×10)/100   ⇒ 1200 = PW × 3   PW = 1200/3 = Rs. 400 Rs. 400nswer : Option Rs. 400
