Ratio of volumes of tetrahedrons having ...

Ratio of volumes of tetrahedrons having coterminus edees `bara+barb,barb+barc,barc+bara" and "bara,barb,barc` respectively is equal to

A

`1:1`

B

`2:1`

C

`3:1`

D

`4:1`

Text Solution

Verified by Experts

The correct Answer is:
2
Ratio=`((1)/(2)[bara+barb,barb+barcbarc+bara])/((1)/(2)[barabarb,barc])`
`((1)/(6)xx2[barabarb,barc])/((1)/(6)[barabarb,barc])=(2)/(1)`
