      B 1050 Correct Answer Incorrect Answer
      C 1262 Correct Answer Incorrect Answer

      Solution

      ATQ,

      Manish's investment = Rs. 0.5x

      According to the question:

      (x × 14 × 2)/100 + [0.5x × 1.12 × 1.12 – 0.5x] = 512

      ⇒ 0.28x + 0.12544x = 512

      ⇒ 0.40544x = 512

      ⇒ x = 1262
