Question

If the sub-duplicate ratio of 6x² : 24y² is ______.

पर्याय

• x : 2y

• 2x : y

• x : y

• y : x

Answer 1

If the sub-duplicate ratio of 6x² : 24y² is x : 2y.

Explanation:

We know that, for any ratio a : b

Sub-duplicate ratio be `sqrt(a) : sqrt(b)`

∴ Sub-duplicate ratio of 6x² : 24y²

= `sqrt(6x^2) : sqrt(24y^2)`

= `sqrt(6x) : 2sqrt(6)y`

= x : 2y
