N140 000 is shared between ABU Kayode and Uche ... - WAEC Mathematics 2007 Question
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 option: b
\(Abu = 2x\
Kayode = x\
Uche = \frac{x}{2}\
2x+x+\frac{x}{2}=140,000\
\frac{7x}{2}=140,000\
7x = 280,000\
x=\frac{280,000}{7}\
x=40,000\)Kayode receives N40,000
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
