N140,000 is shared between ABU, Kayode and Uche. Abu has twice as much as Kayode, and Kayode has twice as much as Uche. What is Kayode’s share?

A.
N80,000 
B.
N40,000 
C.
N20,000 
D.
N10,000
Correct Answer: Option B
Explanation
(Abu = 2x\
Kayode = x\
Uche = frac{x}{2}\
2x+x+frac{x}{2}=140,000\
frac{7x}{2}=140,000\
7x = 280,000\
x=frac{280,000}{7}\
x=40,000)Kayode receives N40,000
