Question

If x, 2, 10 and y are in continued proportion, the values of x and y are respectively:

विकल्प

• 0.2 and 0.25

• 0.2 and 50

• 0.4 and 50

• 0.4 and 25

Answer 1

0.4 and 50

Explanation:

Since x, 2, 10 and y are in continued proportion

∴ ${\displaystyle \frac{x}{2}=\frac{2}{10}=\frac{10}{y}}$

${\displaystyle \Rightarrow x=\frac{2\times 2}{10}}$

= ${\displaystyle \frac{2}{5}}$

= 0.4

And ${\displaystyle y=\frac{10\times 10}{2}=50}$
