In Z ---> 10t = 1g
In Y ---> 6b = 1m

g=1.4m

substituting values
t=(14/100)m
b=(1/6)m
t/b= 21/25

Given,
1) A galok is worth 40% more than a murb, which implies that a galok is worth $1.40. (Let 1 murb=1$)
2) 10 terble coins equal 1 galok, which implies that 10 terble coins are worth a total of $1.40. Therefore each terble coin worth $0.14
3) 6 barbar coins equal 1 murb, which implies that 6 barbar coins equal $1. Therefore each barbar coin worth $1/6.

Required ratio, \(\frac{1 terble}{1 barbar}=\frac{0.14}{(1/6)}\)=0.14*6=0.84=\(\frac{84}{100}\)=\(\frac{21}{25}\)

Ans. (E)
