Question

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

Options

• 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

∴ `x/2 = 2/10 = 10/y`

`\implies x = (2 xx 2)/10`

= `2/5`

= 0.4

And `y = (10 xx 10)/2 = 50`
