Gerard and Martin were both given a pay rise. Gerard was given a 25% pay rise and Martin was given a 5% pay rise. The ratio of Gerard’s salary to Martin’s salary is now 12:7. Martin is now paid £21000. Work out Gerard’s pay before the pay rise

28800

Step-by-step explanation:

first find Gerard's salary and then divide it by 1.25

28800

Step-by-step explanation:

Let M be Martin and G be Gerard

Let 12:7 be 12x:7x

21000 = 7x

x = 3000

12x = 3000*12 = G after pay rise

12x = 36000 = G after pay rise

36000 = 125% G before pay rise

1.25G = 36000

G = 28800

Hope this helps ;)
