  1. Let n be the amount Ronnel started with. After he spent 1/5, he had 4/5 left. Similarly, he had 3/4ths of that amount after more spending. All told, he had:
    (4/5 x 3/4)n=360
    (3/5)n=360
    n=360/(3/5)=600 to start with

  2. Let the money he had at first be x
    Then let be straight forward i.e
    1/5x+(1/4×4/5)x=1
    Then.1/5x+1/5x=1
    Then.2/5x=1
    We can say 1-2/5x= 3/5x
    Then 3/5x=360
    Now x=360×5÷3=600
