45
40
None

Solution:

Concept:

In a ratio

a:b

,

a

is the antecedent and

b

is the consequent.

Explanation:

Given ratio

5:9

and antecedent

25

.

Let the consequent be

x

.

The proportion is

\frac{5}{9} = \frac{25}{x}

.

Cross-multiply:

5x = 9 \times 25

.

So

5x = 225

.

Hence

x = \frac{225}{5} = 45

.

Answer:

The consequent is

45

, which corresponds to option B.
