If A is equal to 20% of B and B is equal to 25% of C. Then what percentage of C equal to A ?

A. 10%

B. 15%

C. 5%

D. 20%

Answer: Option C

Solution(By Examveda Team)

A = 20% of B
A = $$\frac{1}{5}$$ B
$$\frac{A}{B} = \frac{1}{5}$$ ----(i)
B = 25% of C
B = $$\frac{1}{4}$$ C
$$\frac{B}{C} = \frac{1}{4}$$ ----(ii)
Multiply (i) and (ii) We get
$$\frac{A}{B} \times \frac{B}{C} = \frac{1}{5} \times \frac{1}{4}$$
$$\frac{A}{C} = \frac{1}{{20}}$$
Percent of C is equal to A
$$ = \frac{1}{{20}} \times 100 = 5\% $$
