From 1) Let M's wage before increase = x, therefore J's = x+5
After the 6% increase M's = 1.06x and J's = 1.06(x+5)
Subtract: (1.06(x+5)) - 1.06x
Hece BCE out

2) M's wasge = x , J's = y
y/x = 4/3
Two unknows hence cannot find an answer.

Therefore answer is A

1: x+5=J x=M

1.06J-1.06M= 1.06(J-M)

The value of the difference is given in 1, also 1 is sufficient.
2 is insufficient, because it only gives the proportion
