Question

If B is 25% more than A, and C is 20% more than B, then what is A ?

• A. 3:2
• B. 2:3
• C. 5:4
• D. 4:5

Answer 1

Answer:

B. 2:3

Let (A = x).

Since B is 25% more than A:

$B = 1.25x$

Since C is 20% more than B:

$C = 1.20 \times B = 1.20 \times 1.25x = 1.5x$

Therefore,

$A = \frac{C}{1.5} = \frac{2}{3}C$

So A is $(66\tfrac{2}{3}\%)$ of C or $A = (\frac{2}{3}C))$.

=2:3

If you have the value of C, I can calculate the numerical value of A.
