  1. Question 1

    Q1. The ratio in which the price at Rs. 7.20 a kg be mixed with rice at Rs. 5.70 a kg to produce

    • A) mixture worth Rs. 6.30 a kg is _________? Mixtures 1:2
    • B) 3:02
    • C) 2:03
    • D) 4:05

    Answer: 2:03

    Explanation: Using alligation with mixture cost = 68.20/1.10 = 62... wait, the target price is Rs. 6.30. By alligation: (7.20−6.30) : (6.30−5.70) = 0.90 : 0.60 = 3:2, so the ratio of cheaper to dearer is 2:3.
