\begin{array}{l l} \text{Column A} & \text{Column B} \\ 14 : x = 10 : 15 & x = 42 \end{array}

Solution:

Concept:

A ratio equality is solved by cross-multiplication, then compare the resulting

x

with

42

Explanation:

Given:

14 : x = 10 : 15

Write as fractions:

\frac{14}{x} = \frac{10}{15}

Simplify:

\frac{14}{x} = \frac{2}{3}

Cross-multiply:

14 \times 3 = 2x

So,

42 = 2x

Therefore,

x = 21

Column A value

= 21

Column B value

= 42

Since

21 < 42

, Column B is greater.

Answer:

Column B is greater, so the correct option is B.
