Question

A gets double of what B gets and B gets double of what C gets. Find A : B and B : C
and verify whether the result is in proportion or not.

Answer 1

Answer:

A : B and B : C are in proportion

Step-by-step explanation:

Let say C gets =  X

Then B gets  = 2X

Then A gets = 2(2X) = 4X

A : B :: B : C

=> 4X : 2X :: 2X  : X

these would be in the proportion if

iff

4X * X  = 2X * 2X

=> 4X² = 4X²

which is true

hence A : B and B : C are in proportion
