Using proportions, it is found that 5449.62 QR is equal to HKD 315920.
Hence, the rule of three is:
2000 QR - 157960 NC
x QR - 13.62 NC
Applying cross multiplication:
[tex]157960x = 200(13.62)[/tex]
[tex]x = \frac{200(13.62)}{157960}[/tex]
[tex]x = 0.01725[/tex]
Then:
Then, the second rule of three is:
1 HKD - 0.01725 QR
315920 HKD - x QR
Applying cross multiplication:
[tex]x = 0.01725(315920) = 5449.62[/tex]
5449.62 QR is equal to HKD 315920.
