Question

divide 7000 among A,B and C such that A gets 50%of what B gets and B gets 50% of what c gets

Answer 1

let C's share=20A,

then
B's share= 50% of C's share,

B's share=50/100 × 20A,

=10A,

then
A's share=50% of B's share,

A's share=50/100 × 10A,

=5A,

hence ratio of A, B and C shares=5A:10A:20A,

=1:2:4,

therefore
C's share =7000×4/7,

=1000×4=4000

Answer 2

Let the amount C get be x

The amount B gets = 0.5x

The amount A gets = (0.5)(0.5x) = 0.25x

The total amount to be divided is 7000:

x + 0.5x + 0.25x = 7000

1.75x = 7000

x = 7000 ÷ 1.75 = 4000

Find the amount c gets:

C = x = 4000

Answer: C got 4000
