    A A = Rs 160, B = Rs 200, C = Rs 200 Correct Answer Incorrect Answer
    B A = Rs 160, B = Rs 200, C = Rs 280 Correct Answer Incorrect Answer
    C A = Rs 260, B = Rs 200, C = Rs 280 Correct Answer Incorrect Answer
    D A = Rs 160, B = Rs 100, C = Rs 280 Correct Answer Incorrect Answer

    Solution

    Let their wages be 4k, 5k, 7k. Total = 4k + 5k + 7k = 16k = 640 ⇒ k = 640 / 16 = 40 So: A = 4k = 4 × 40 = 160 B = 5k = 5 × 40 = 200 C = 7k = 7 × 40 = 280 Answer: A = Rs 160, B = Rs 200, C = Rs 280.
