  1. Person A – 80 in 7 Hours = 960 in 84 Hours

    Person B – 90 in 12 Hours = 720 in 84 Hours

     

    Ratio = 960:720 = 4:3

  2. Anand earns Rs. 80 in 7 hours.

    Anand earns Rs. 80/7 in 1 hour.

    Promode earns Rs. 90 in 12 hours.

    Promode earns Rs. 90/12 in 1 hours.

    Ratio of their earnings = 80/7 : 90/12

    => 80 * 12 : 90 * 7

    => 8 * 12 : 9 * 7

    => 96 : 63

    => 32 : 21.

    Ratio of their earnings = 32 : 21.
