C II and III together Correct Answer Incorrect Answer
D I and III together Correct Answer Incorrect Answer
E All I, II and III Correct Answer Incorrect Answer

Solution

From I: SI after 10 years is Rs 1200, so after 1 year = 1200/10 = Rs 120 so,SI of 1 year = Rs. 120 From III: Principal = 15 × S.I after 3 years or P = 15 ×P×R ×3/100 or R = 100/45% So from I and II, SI =120 = P×R×1/100 = P ×(100/45) /100 So we can find Principal. then we can find the required amount by CI formula So from I and II, SI =120 = P×R×1/100 = P ×(12) /100 So we can find Principal, then we can find the required amount by CI formula
