Answer 2

Correct Question: A is 60% of B and B is 30% of C. what percentage of C is A.

Answer:

A is 18% of C.

Step-by-step explanation:

According to the question,

A is 60% of B, i.e.,

A = 60% of B

  = 60% × B

Simplify as follows:

A = $\frac{60}{100}\times B$

A = $\frac{3B}{5}$ . . . . . (1)

Now,

B is 30% of C, i.e.,

B = 30% of C

  = 30% × C

Simplify as follows:

B = $\frac{30}{100}\times C$

B = $\frac{3C}{10}$ . . . . . (2)

Substitute the value of B in the equation (1) as follows:

⇒ A = $\frac{3(\frac{3C}{10} )}{5}$

Now, simplify as follows:

⇒ A = $\frac{9C}{50}$

Percentage of A in terms of C,

A = $\frac{9C}{50}$ × 100%

A = 18% of C

Therefore, 18% of C is A.
