Question:

If 0.04 : 0.06 :: 0.06 : A, then what is the value of A?

Options:

0.05

0.08

0.06

0.09

Correct Answer:

0.09

Explanation:

0.04 : 0.06 :: 0.06 : A

In a proportion, the product of middle terms = product of extreme terms

0.06 x 0.06 = 0.04 x A

A = $\frac{0.06\; \times\; 0.06}{0.04}$

= 0.09
