A nuggest of gold and quartz was found to contain x g of gold y g of quartz and has density d. If the densities of gold and quartz are `d_(1)` and `d_(2)` respectively, then the correct relations is:

A

`x/d_(1) + y/d_(2) = (x + y)/(d)`

B

`xd_(1) + yd_(2) = (x + y)d`

C

`(x)/(d_(2)) + y/(d_(1)) = (x +y)/(d)`

D

`(x + y)/(d) + x/d_(1) + x/d_(2) = 0`
