Answer:

£28,000

Step-by-step explanation:

Martin’s salary is 7/12 of Gerard’s salary. So, you have to multiply by the reciprocal, which is 12/7.

[tex]\frac{12}{7}[/tex]×21,000 = 12×3000=36,000

Since Gerard salary was multiplied by 5/4, multiply by 4/5.

[tex]\frac{4}{5}[/tex]×36,000 = 4×7200=28,000
