1.    R365 134 ÷ R60 613 = 6,02 times more

2.    79,2% ÷ 8,9% = 8,88 ≈ 9

3.    Mean = sum ÷ 4

    = 789 460 ÷ 4

    = 197 365

4.    The original amount was multiplied by 113%. This increase would then be added onto the original amount to give a new amount that was 2,13 times the original amount (100% + 113%).
