Answer:
126
Step-by-step explanation:
28% of x = 63 less than 84% of x
[tex] \frac{28}{100}x = 63[/tex]
Applying cross multiplication rule,
[tex]28x = 100 \times 63[/tex]
[tex]28x = 6300[/tex]
Divide through by 28
[tex] \frac{28x}{28} = \frac{6300}{28} [/tex]
[tex]x = 225[/tex]
To check, 28% of 225 is 63
Since x = 225,
84% of 225 implies
[tex] \frac{84}{100} \times 225 = 189[/tex]
That is, 84% of 225 =189
Hence, 28% of x less than 84% of x implies
[tex]189 - 63 = 126[/tex]
