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'sshare?
A
N80,000
B
N40,000
C
N2,000
D
10,000
correct option: b

Let Abu's share = 2x;

Kayode's = x

Uche's share = (\frac{x}{2})

Total: 2x + x + (\frac{x}{2}) = N140,000

(\frac{7x}{2}) = N140,000

x = (\frac{280,000}{7}) = N40,000

Kayode's share = N40,000
