Answer 2

C is 6.25% of A.

Step-by-step explanation:

Given : If A is 80% of B and B is 20% of C.

To find : What percent of A is C ?

Solution :

A is 80% of B.

i.e. $A=\frac{80}{100}B$

$A=0.8B$ ....(1)

B is 20% of C.

i.e. $B=\frac{20}{100}C$

$B=0.2C$ .....(2)

Substitute B from (1) into (2),

$\frac{A}{0.8}=0.2C$

$C=\frac{A}{0.8\times 0.2}$

$C=\frac{A}{0.16}$

$C=6.25\%A$

Therefore, C is 6.25% of A.
